| % |
| % 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. |

| % 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. |
