Short description:
ctable.sty provides commands to easily typeset centered or left or right
aligned tables and (multiple-)figure floats, with footnotes. Instead of an
environment, a command with 4 arguments is used; the first is optional and
is used for key,value pairs generating variations on the defaults and
offering a route for future extensions.

% \begin{abstract}\noindent
% The \texttt{ctable} package provides a \texttt{ctable}
% command for the typesetting of table and figure floats. You will
% not need to type the usual nested begin...end sequences, as
% \texttt{ctable} is a command, not an environment. \texttt{ctable}
% has only 4 arguments, but the optional first one may hold many
% \textsl{key=value} pairs and makes \texttt{ctable} very flexible
% and extensible. It uses Simon Fear's \REF{booktabs} package for
% better vertical spacing around horizontal rules and it provides
% facilities for making table footnotes.
% \end{abstract}
% \tableofcontents
% \section{Introduction}
%
% \section{Purpose} The |ctable| package lets you easily typeset
% captioned table and figure floats with optional
% footnotes. Both caption and footnotes will normally be forced within the
% width of the table.
% If the width of the table is specified, then \REF{tabularx} will be used
% to typeset it, and one or more |X| column specifiers should be specified.
% Otherwise tabular will be used.
%
% This package defines the commands |\ctable|, |\tnote| and
% |\tmark|, and four |\tabularnewline| generating
% commands. The latter generate reasonable amounts of whitespace
% around horizontal rules and are also useful for tabulars
% outside this package.
%
% Since the |ctable| package imports the \REF{array} and \REF{booktabs}
% packages, all commands from those packages are available as well.
%
% Note that, in line with the comments that Simon Fear made
% describing his \REF{booktabs} package, vertical rules for column
% separation can be produced with |\ctable|, but no provisions are
% made to have them make contact with horizontal rules.
%
% \section{Usage}
% \DescribeMacro{\setupctable}
% |\ctable| defaults can be set, either in the preamble or in the body,
% with:\\
%
% |\setupctable{options} % key=value,...|\\
%
% \DescribeMacro{\ctable}
% |\ctable| is called with 4 parameters, of which the first is optional: \\
%
% |\ctable[options] % key=value,...|\\
% | {coldefs} % for \begin{tabular}|\\
% | {foottable} % zero or more \tnote commands (see below)|\\
% | {table rows} % rows for the table|\\
%
% Options are given as key=value pairs, separated by comma's.
% Extra comma's, including one behind the last pair, don't hurt.
% Arguments to option should be put between braces if they contain
% comma's or equals signs.
% \section{Options}
% Currently the following option keys have been defined:
%
% { \marginparwidth25mm
% \DescribeMacro{bgopacity=...\hfill}
% Sets the opacity of the table's background color, where 1 is 100\% opaque
% (the default), and 0 is completely transparent. One application is with
% watermarking: most watermarking packages print their watermark on the
% background. |ctable|'s background color, which is opaque by default, may
% make the watermark (partially) invisible. You can avoid this by setting
% the |bgopacity| option to a value lower than 1. Note that this works only
% in PDF mode, a warning is issued otherwise.\\
% Note: there are two limitations to transparency setting:
% \begin{compactenum}
% \item it works only in PDF mode: so it works in pdflatex and lualatex,
% but is disabled in xelatex.
% \item it disables transparency features in the tikz package; therefore,
% ctable checks if the tikz package is loaded and if so, disables its own
% transparency with a warning. That helps only if you load tikz
% \textit{before} ctable.
% \end{compactenum}
%
% \DescribeMacro{botcap\hfill}
% put the caption at the bottom of the float instead of on top of it.
% See also: |topcap|, |sidecap|.
%
% \DescribeMacro{caption=...\hfill}
% table caption; the braces are needed only if your caption contains a
% comma or an equals sign.
%
% \DescribeMacro{cap=...\hfill}
% for a short caption to go to the |\listoftables|. Without the |cap|
% option, the full caption will go into the |\listoftables|. If |cap| is
% given an empty value, \textsl{and you have loaded the |caption| package},
% no entry in the |\listoftables| will be made. This may be useful, for
% example, with the |continued| option.
%
% \DescribeMacro{captionskip=...\hfill}
% moves the caption relative to the table; the default is |0ex|, which puts
% captions at their default \LaTeX\ positions. For the standard \LaTeX\
% classes this means that a top caption's baseline at
% |1ex| above the top rule position of the table and a bottom caption's
% baseline at |4ex| below the bottom rule position. These dimensions may be
% different for other classes or when other packages are included. The
% |memoir| class and the |caption| package, for example, both typeset
% captions differently, and the combination of both even differs from each
% alone.\footnote{I did some measurements on the whitespace between the
% caption and the top of the table with and without using the caption
% package and/or the memoir class: standard LaTeX: 1ex; memoir:
% 2.32ex; caption: 2.69ex; both memoir and caption: 2.68ex. For the
% distances between bottom caption baselines and the table bottom I found,
% respectively: 3.90ex, 3.41ex, 3.72ex and 3.74ex } Keep in mind that when
% you use the |caption| package in the |memoir| class, |memoir|'s caption
% commands are suspended and |caption|'s commands must be used.
%
% \DescribeMacro{captionsleft\hfill} This option is defined for
% |\setupctable| only, and it is effective only where the |sideways| option
% is used. After |\setupctable{captionsleft}| all tables typeset with the
% |sideways| option will have their captions at the left.
%
% \DescribeMacro{captionsright\hfill} This option is defined for
% |\setupctable| only, and it is effective only where the |sideways| option
% is used. After |\setupctable{captionsright}| all tables typeset with the
% |sideways| option will have their captions at the right.
%
% \DescribeMacro{captionsinside\hfill}
% This option is defined for |\setupctable| only, it is the default, and it is effective
% only where the |sideways| option is used. After
% |\setupctable{captionsinside}| all tables typeset with the |sideways|
% option will have their captions at the left in one-sided documents. In
% twosided documents, captions will be on the left for odd-numbered pages
% and on the right for even-numbered pages. This is the default.
%
% \DescribeMacro{center\hfill}
% center the table in the available text width; this is the default.
% See also: |left|, |right|.
%
% \DescribeMacro{continued=...\hfill}
% if used, the table will be numbered the same as the previous table. If
% used without an argument, the caption will be suffixed with `
% (continued)', if used with an argument, the suffix will be the argument.
%
% \DescribeMacro{doinside=...\hfill}
% command to be run inside, just before the tabular or tabularx
% environment. You can use this, for example, for the adjustment of the
% font size with |\small|.
%
% \DescribeMacro{figure\hfill}
% produce a figure float instead of a table float. See also: |table|.
%
% \DescribeMacro{footerwidth=...\hfill}
% Footnotes are typeset within the width of the table. When you use the
% |mincapwidth| option, presumably because the table is very narrow, footnotes
% are given the same width as the caption. With small footnotes this may not
% be what you want; this option can be used to give the footnotes their own width.
% Without an argument, they will be typeset within the width of of the table.
%
% \DescribeMacro{framebg={\slshape r g b}\hfill}
% set the background color of the frame (the color inside the frame) to the
% given triplet of \textsl{rgb}-values. The values should be numbers
% between 0 and 1. The default is |1 1 1| (white).
%
%
% \DescribeMacro{framefg={\slshape r g b}\hfill}
% set the foreground color of the frame (the rule color) to the given
% triplet of \textsl{rgb}-values. The values should be numbers between 0
% and 1. The default is |0 0 0| (black).
%
%
% \DescribeMacro{framerule=...\hfill}
% draw a frame around the table with the given rule thickness. The default
% is |0pt|, so that no frame will be seen.
%
%
% \DescribeMacro{framesep=...\hfill}
% set the distance between the frame and the table to the given dimension.
% The default is |0pt|.
%
%
% \DescribeMacro{label=...\hfill}
% labels the float with |\label|.
%
% \DescribeMacro{left\hfill}
% left align the table in the available text width. See also: |center|, |right|.
%
% \DescribeMacro{maxwidth=...\hfill}
% like the \textsl{width} option, but any |X| column specifiers will be
% replaced with |l| if the resulting table width would thus stay within the
% specified maximum width. This is especially useful where the \LaTeX\
% source is generated by a script.
%
% \DescribeMacro{mincapwidth=...\hfill}
% sets the minimum width of the float. Without this option, the width is
% set to that of the tabular, and the caption and footnotes are typeset
% within that width. This may be a problem with very narrow tables;
% |mincapwidth| can then be used to give the float a minimum width. The
% tabular will be centered in it. If you don't want the footnotes to be affected
% see the |footerwidth| option.
%
% \DescribeMacro{nonotespar\hfill}
% typeset footnotes in a table; this is the default. See also: |notespar|.
%
% \DescribeMacro{nosideways\hfill}
% undo the sideways option. See also: |sideways|.
%
% \DescribeMacro{nostar\hfill}
% use the un-starred versions of the |table| and |figure| environments;
% this is the default
%
% \DescribeMacro{nosuper\hfill}
% in the footnote table, typeset footnote markers on the line, instead of
% superscripted.
%
% \DescribeMacro{notespar\hfill}
% typeset footnotes in a paragraph instead of in a table.
%
% \DescribeMacro{pos=...\hfill}
% float position, default: |tbp|.
%
% \DescribeMacro{right\hfill}
% right align the table in the available text width.
%
% \DescribeMacro{sidecap\hfill}
% put the caption at the side of the float. Currently, this works only if
% you have loaded the |memoir| class, otherwise an error message is
% generated. The parameters for the caption, such as its vertical
% positioning, width and more, must be set with the appropriate |memoir|
% commands. See also: |botcap|, |topcap|.
%
% \DescribeMacro{sideways\hfill}
% rotate table or figure by 90 degrees anticlockwise and put it on a
% separate page. With the twoside option for the standard \LaTeX\ document
% classes, rotation will be -90 on even pages, unless the options
% |captionleft| or |captionsright| are used. If you use this option, the
% |pos| option is not allowed. See also: |nosideways|, |captionsinside|.
%
% \DescribeMacro{star\hfill}
% use the starred versions of the |table| and |figure| environments, which
% place the float over two columns when the |twocolumn| option or the
% |\twocolumn| command is active. See also: |nostar|.
%
% \DescribeMacro{super\hfill}
% in the footnote table, typeset footnote markers as superscripts; this is
% the default. See also: |nosuper|.
%
% \DescribeMacro{table\hfill}
% produce a table float (this is the default). See also: |figure|.
%
% \DescribeMacro{topcap\hfill}
% put the caption top of the float; this is the default. See also: |botcap|, |sidecap|.
%
% \DescribeMacro{width=...\hfill}
% \REF{tabularx} will be used to typeset the table at the specified
% width\,---\,one or more |X| column specifiers must be provided.
%
% }
%
% \section{The width and maxwidth options}
% When \LaTeX-sources containing tables are generated automatically by a
% script, it is often not known in advance what the maximum size of an
% |l|~column will be. A good solution for this is to use an |X|~specifier,
% typesetting the table at the text width with the \REF{tabularx} package.
% However, this will result in too much white space in cases where the
% column contains small texts only. This problem can be solved by using
% the maxwidth option instead of the width option. The |X|~specifiers will
% then be replaced with |l| as long as the width of the resulting table
% stays with the specified maximum width.
%
% \section{Tables wider than the text width}
% When you make a table wider than |\textwidth|, it will extend in the right margin.
% If it is a large table, occupying a whole page, you can use the geometry package
% and surround your ctable call with |\newgeometry{width=...,margin=...}| and |\restoregeometry|.
% However, both geometry commands imply |\clearpage|, so your table will appear on an otherwise
% empty page.
%
% Alternatively, you can center the table on the paper, extending in both margins, by using the
% option |doinside=\hspace*{<dimen>}| with an appropriate negative |dimen>|.
%
% \section{Setting option defaults: setupctable}
% Every call of |\ctable| resets the options to their defaults before evaluating the
% first (optional) argument. So if you make two ctables: |\ctable[left,...| and
% |\ctable[...|, the first will be left-aligned on the page, but the second, lacking
% the |left| option, will be centered, because that is the default. If you want all
% your tables left-aligned, it's more practical to change the default by calling
% \DescribeMacro{\setupctable}
% |\setupctable{left}|, either in the preamble or somewhere in the body. In latter
% case only tables following the call will have their defaults changed. \par
% |\setupctable| can set the defaults for all options except (of course) |caption|,
% |cap|, and |label|. Actually, the initial option defaults are set by
% calling |\setupctable| as follows:
% \begin{verbatim}
% \setupctable{
% captionskip=0pt, framerule=0pt, nostar,
% center, framesep=0pt, pos=tbp,
% continued=(continued), maxwidth=0pt, super,
% doinside={}, mincapwidth=0pt, table,
% framebg=1 1 1, nonotespar, topcap,
% framefg=0 0 0, nosideways, width=0pt
% }
% \end{verbatim}
% \section{Other commands}
% \DescribeMacro{\tnote}
% |\tnote[label]{footnote text}| places {\footnotesize
% \textsuperscript{\normalfont\textit{label}}\,footnote text}
% under the table.
% This command can only be used in |\ctable|'s third argument, i.e.\ the foottable
% argument described above. The
% label is optional, the default label is a single $a$. For more
% detailed control, you can also replace this command with something
% like |labeltext&footnotetext\NN|.
% The footnotes are placed under the table, without a rule.
% You therefore probably will want to use the |\LL| (last line)
% command if you use footnotes.
% \par
% \DescribeMacro{\tmark}
% |\tmark[label]| this command places the superscripted label in the
% table. It is equivalent with |$^{label}$|.
% The label is optional, the default label is a single $a$.
% |\tmark| may be used in captions, but only \textit{without} an argument.
% \par
% The newline generating commands are a combination of
% |\tabularnewline| and zero or one of \REF{booktabs} |\toprule|,
% |\midrule| or |\bottomrule|. These combinations have been made, and
% short names have been defined, because source texts for complex
% tables often become very crowded:
% \par
% \DescribeMacro{\NN} Normal Newline, generates just a normal new line.
% An optional dimen parameter inserts extra vertical space under the
% line. Is an alias for |\tabularnewline|
% \par
% \DescribeMacro{\FL} First Line, generates a new line and a thick
% rule with some extra space under it.
% An optional dimen parameter sets the line width; the default is 0.08em.
% Is an alias for |\toprule|
% \par
% \DescribeMacro{\ML} Middle Line: generates a new line and a thin
% rule with some extra space over and under it.
% An optional dimen parameter sets the line width; the default is 0.05em.
% Is an alias for |\tabularnewline\midrule|
% \par
% \DescribeMacro{\LL} Last Line: generates a new line and a thick
% rule with some extra space over it.
% An optional dimen parameter sets the line width; the default is 0.08em.
% Is an alias for |\tabularnewline\bottomrule|
% \par
% These macros can be used outside |\ctable| constructs.
% \par
% Finally, for completeness, here are some of \REF{booktabs}' commands
% that may be useful:
% \par
% \DescribeMacro{\toprule} |\toprule[<wd>]|
% where |<wd>| is the optional thinkness of the rule.
% \par
% \DescribeMacro{\midrule} |\midrule[<wd>]|.
% \par
% \DescribeMacro{\bottomrule} |\bottomrule[<wd>]|.
% \par
% \DescribeMacro{\cmidrule} |\cmidrule[<wd>](<trim>){a-b}|
% where |<trim>| can be |r|, |l|, or |rl|

% Table~\ref{width} is an example with a width specification,
% taken from the \REF{tabularx} documentation, with the vertical rules
% removed.
% By using the trimming parameters of the \REF{booktabs} |\cmidrule|

% The |left| option left aligns the table. It was typeset with:
% \color{vbgreen}
% \begin{verbatim}

%
% Figures, even single ones, are always put in tabular cells. This is not
% particularly handy for single pictures, but it eases the construction of
% arrays of pictures, including sub-captions, delineation, and spacing. For a
% small example, which also shows how you can simplify the construction of
% figure arrays, see subsection~\ref{figureexample} on
% page~\pageref{figureexample}.
%
% \section{Option examples}
% In the following, small examples will be shown illustrating the effect of
% options. In the left column the relevant part of the source is shown, in the
% right column you see the result. In most cases you see a standard example on a
% light yellow background, followed by one or more variations on a light blue
% background. Where necessary, the example will show boxes to indicate the page
% and the text body.
%
% \subsection{\ttfamily\bfseries center, left, right}
% These options align the float in the page; the default is |center|:
% \medskip\\
% \ROW{Y}{s02k}{02k}
% \ROW{B}{s02l}{02l}
% \ROW{B}{s02m}{02m}
%
% \subsection{\ttfamily\bfseries super, nosuper}
% Footnote markers in |ctable| are typeset superscripted by default. Use the
% |nosuper| option to place them on the base line:
% \medskip\\
% \ROW{Y}{s07a}{07a}
% \ROW{B}{s07b}{07b}
%
% \subsection{\ttfamily\bfseries notespar, nonotespar}
% By default, footnotes in |ctable| are typeset in a table, one line per note.
% This corresponds with the |nonotespar| option.You can also typeset them in a paragraph,
% one after the other, by using the |notespar| option:
% \medskip\\
% \ROW{Y}{s12a}{12a}
% \ROW{B}{s12b}{12b}
%
% \subsection{\ttfamily\bfseries continued}
% The |continued| option suffixes the caption with ` (continued)', and lowers the table
% number by one, so that it obtains the same number as the previous table.
% This option can be given an argument to replace the default suffix:
% \medskip\\
% \ROW{Y}{s13a}{13a}
% \ROW{B}{s13b}{13b}
% \ROW{B}{s13c}{13c}
%
% \subsection{\ttfamily\bfseries mincapwidth}
% |ctable| forces caption and footnotes to stay within the width of the table.
% Sometimes, however, tables are so narrow, that this is not really what you want.
% In such cases, use the |mincapwidth| option to give caption and footnotes some
% extra room:
% \medskip\\
% \ROW{Y}{s05a}{05a}
% \ROW{B}{s05b}{05b}
% \medskip
% You can set |mincapwidth| to a large value, say |\hsize|, if you want a one-line
% caption. Note, however, that this may influence the horizontal positioning of
% the table: values larger than |\hsize| will move a centered table out of the
% center, a value of |\hsize| will prevent the |left| and |right| options to do
% their work, because the table is already captured between the left and right
% margins. When footnotes are small, you may wish to undo the effect of the
% |mincapwidth| option on them:
% \medskip\\
% \ROW{B}{s05c}{05c}
% \medskip
%
% \subsection{\ttfamily\bfseries maxwidth}
% When \LaTeX-sources containing tables are generated automatically by a
% script, it is often not known in advance what the maximum size of an |l|
% column will be. A good solution for this is to use an |X| specifier,
% typesetting the table at the text width with the \REF{tabularx} package.
% However, this will result in too much white space in cases where the
% column contains small texts only. This problem can be solved by using
% the maxwidth option instead of the width option. The |X| specifiers will
% then be replaced with |l| as long as the width of the resulting table
% stays with the specified maximum width.
% \medskip\\
% \ROW{Y}{s06a}{06a}
% \ROW{B}{s06b}{06b}
%
% \subsection{\ttfamily\bfseries framerule}
% The following examples show the use of frames and backgrounds. Every table
% is typeset by |ctable| with a frame around it, but the frame is, by default,
% drawn with a zero width line, and is therefore invisible. You can make it
% visible by either changing the linewidth to a positive value or by giving it a
% background color, which will be used to fill the frame.
%
% Here is a simple table without a frame, followed by one with a red, |1pt| thick
% frame:
% \medskip\\
% \ROW{Y}{s08a}{08a}
% \ROW{B}{s08b}{08b}
% \medskip
% As you see, the frame fits closely to the first (|\FL|) and last (|\LL|) table
% lines. This can be a reason to either remove those lines, or to introduce some
% whitespace between the frame and the table with the |framesep| option:
% \medskip\\
% \ROW{B}{s09b}{09b}
% \medskip
% And finally, we could also frame the table by giving it a, say, yellow backgound
% instead of a red frame line, or even do both:
% \medskip\\
% \ROW{Y}{s10a}{10a}
% \ROW{B}{s10b}{10b}
%
% \newpage
% \subsection{\ttfamily\bfseries captionskip}
% The distance between a top caption and the table is \texttt{2ex},
% but it can be varied with \texttt{captionskip}:
% \medskip\\
% \ROW{Y}{s03a}{03a}
% \ROW{B}{s03b}{03b}
% \medskip
% This works for bottom caption, too:
% \medskip\\
% \ROW{Y}{s04a}{04a}
% \ROW{B}{s04b}{04b}
%
% \subsection{\ttfamily\bfseries figure, botcap}\label{figureexample}
% By default, |ctable| generates a table float, but with the |figure| option, a
% figure float is generated instead. The caption stays on top, so if you are
% accustomed to have bottom caption for your figures, you will probably also need
% the |botcap| option:
% \medskip\\
% \ROW{Y}{s01a}{01a}
% \ROW{B}{s01b}{01b}
%
% \newpage
% \subsection{\ttfamily\bfseries doinside}
% The argument of doinside is supposed to be a command to be run inside,
% just before the tabular or tabularx environment. You can use this, for
% example, for the adjustment of the font size with |\small|:
% \medskip\\
% \ROW{Y}{s14a}{14a}
% \StopEventually{}
