% |
% Please try the latest version of texinfo.tex before submitting bug |
% reports; you can get the latest version from: |
% http://www.gnu.org/software/texinfo/ (the Texinfo home page), or |
% ftp://tug.org/tex/texinfo.tex |
% (and all CTAN mirrors, see http://www.ctan.org). |
% The texinfo.tex in any given distribution could well be out |
% of date, so if that's what you're using, please check. |

% Send bug reports to bug-texinfo@gnu.org. Please include including a |
% complete document in each bug report with which we can reproduce the |
% problem. Patches are, of course, greatly appreciated. |
% |
% To process a Texinfo manual with TeX, it's most reliable to use the |
% texi2dvi shell script that comes with the distribution. For a simple |
% manual foo.texi, however, you can get away with this: |
% tex foo.texi |
% texindex foo.?? |
% tex foo.texi |
% tex foo.texi |
% dvips foo.dvi -o # or whatever; this makes foo.ps. |
% The extra TeX runs get the cross-reference information correct. |
% Sometimes one run after texindex suffices, and sometimes you need more |
% than two; texi2dvi does it as many times as necessary. |
% |
% It is possible to adapt texinfo.tex for other languages, to some |
% extent. You can get the existing language-specific files from the |
% full Texinfo distribution. |

% @multitable macros |
% Amy Hendrickson, 8/18/94, 3/6/96 |
% |
% @multitable ... @end multitable will make as many columns as desired. |
% Contents of each column will wrap at width given in preamble. Width |
% can be specified either with sample text given in a template line, |
% or in percent of \hsize, the current width of text on page. |
|
% Table can continue over pages but will only break between lines. |
|
% To make preamble: |
% |
% Either define widths of columns in terms of percent of \hsize: |
% @multitable @columnfractions .25 .3 .45 |
% @item ... |
% |
% Numbers following @columnfractions are the percent of the total |
% current hsize to be used for each column. You may use as many |
% columns as desired. |
|
|
% Or use a template: |
% @multitable {Column 1 template} {Column 2 template} {Column 3 template} |
% @item ... |
% using the widest term desired in each column. |
|
% Each new table line starts with @item, each subsequent new column |
% starts with @tab. Empty columns may be produced by supplying @tab's |
% with nothing between them for as many times as empty columns are needed, |
% ie, @tab@tab@tab will produce two empty columns. |
|
% @item, @tab do not need to be on their own lines, but it will not hurt |
% if they are. |
|
% Sample multitable: |
|
% @multitable {Column 1 template} {Column 2 template} {Column 3 template} |
% @item first col stuff @tab second col stuff @tab third col |
% @item |
% first col stuff |
% @tab |
% second col stuff |
% @tab |
% third col |
% @item first col stuff @tab second col stuff |
% @tab Many paragraphs of text may be used in any column. |
% |
% They will wrap at the width determined by the template. |
% @item@tab@tab This will be in third column. |
% @end multitable |
|
% Default dimensions may be reset by user. |
% @multitableparskip is vertical space between paragraphs in table. |
% @multitableparindent is paragraph indent in table. |
% @multitablecolmargin is horizontal space to be left between columns. |
% @multitablelinespace is space to leave between table items, baseline |
% to baseline. |
% 0pt means it depends on current normal line spacing. |
