- %% V1.0 was distributed anonymously, based on a Usenet posting that was
- %% not intended for stand-alone use.
- %% V1.1 was modified by Piet van Oostrum <piet@cs.uu.nl> to allow it to
- %% work without bigstrut.sty.
- %% V1.2 was modified by Jerry Leichter for the same goal, but using a
- %% different approach which will work properly in conjunction with
- %% bigstrut.sty.
- %% V1.2a was modified by Piet van Oostrum <piet@cs.uu.nl> to use \vskip
- %% instead of \raise in positioning, avoiding making rows too high
- %% when the adjustment is large.
- %% V1.3 was modified by Piet van Oostrum to work properly in a p{} column
- %% (\leavevmode added)
- %% V1.4 was modified by Piet van Oostrum to check for the special case that
- %% the width is given as an *. In this case the natural
- %% width of the text argument will be used and the argument
- %% is processed in LR-mode.
- %% V1.5 was modified by Piet van Oostrum: Added a % after \hbox{#5}\vfill}.
- %% Added \struts around #5 for better vertical positioning.
- %% Additional coding for negative value of nrows.
- %
- % Make an entry that will span multiple rows of a table.
- %
- % \multirow{nrows}[bigstruts]{width}[fixup]{text}
- %
- % nrows is the number of rows to span. It's up to you to leave the other
- % rows empty, or the stuff created by \multirow will over-write it.
- % With a positive value of nrows the spanned colomns are this row and
- % (nrows-1) rows below it. With a negative value of nrows they are
- % this row and (1-nrows) above it.
- %
- % bigstruts is mainly used if you've used bigstrut.sty. In that case it
- % is the total number of uses of \bigstrut within the rows being
- % spanned. Count 2 uses for each \bigstrut, 1 for each \bigstrut[x]
- % where x is either t or b. The default is 0.
- % width is the width to which the text is to be set, or * to indicate that
- % the text argument's natural width is to be used.
- %
- % text is the actual text. If the width was set explicitly, the text will
- % be set in a parbox of that width; you can use \\ to force linebreaks
- % where you like.
- %
- % If the width was given as * the text will be set in LR mode. If you
- % want a multiline entry in this case you should use a tabular or array
- % in the text parameter.
- %
- % The text is centered vertically within the range spanned by nrows.
- %
- % fixup is a length used for fine tuning: The text will be raised (or
- % lowered, if fixup is negative) by that length above (below) wherever
- % it would otherwise have gone.
- %
- % For example (using both multirow and bigstrut)
- %
- % \newcommand{\minitab}[2][l]{\begin{tabular}{#1}#2\end{tabular}}
- % \begin{tabular}{|c|c|}
- % \hline
- % \multirow{4}{1in}{Common g text} & Column g2a\\
- % & Column g2b \\
- % & Column g2c \\
- % & Column g2d \\
- % \hline
- % \multirow{3}[6]*{Common g text} & Column g2a\bigstrut\\\cline{2-2}
- % & Column g2b \bigstrut\\\cline{2-2}
- % & Column g2c \bigstrut\\
- % \hline
- % \multirow{4}[8]{1in}{Common g text} & Column g2a\bigstrut\\\cline{2-2}
- % & Column g2b \bigstrut\\\cline{2-2}
- % & Column g2c \bigstrut\\\cline{2-2}
- % & Column g2d \bigstrut\\
- % \hline
- % \multirow{4}*{\minitab[c]{Common \\ g text}} & Column g2a\\
- % & Column g2b \\
- % & Column g2c \\
- % & Column g2d \\
- % \hline
- % \end{tabular}
- %
- % If any of the spanned rows are unusually large, or if you're using
- % bigstrut.sty and \bigstrut's are used assymetrically about the centerline of
- % the spanned rows, the vertical centering may not come out right. Use the
- % fixup argument in this case.
- %
- % Just before "text" is expanded, the \multirowsetup macro is expanded to
- % set up any special environment. Initially, \multirowsetup contains just
- % \raggedright. It can be redefined with \renewcommand.
- %
- % Bugs: It's just about impossible to deal correctly with descenders. The
- % text will be set up centered, but it may then have a baseline that doesn't
- % match the baseline of the stuff beside it, in particular if the stuff
- % beside it has descenders and "text" does not. This may result in a small
- % missalignment. About all that can be done is to do a final touchup on
- % "text", using the fixup optional argument. (Hint: If you use a measure
- % like .1ex, there's a reasonable chance that the fixup will still be correct
- % if you change the point size.)
- %
- % \multirow is mainly designed for use with table, as opposed to array,
- % environments. It will not work well in an array environment since the lines
- % have an extra \jot of space between them which it won't account for. Fixing
- % this is difficult in general, and doesn't seem worth it. The bigstruts
- % argument can be used to provide a semi-automatic fix: First set
- % \bigstrutjot to .5\jot. Then simply repeat nrows as the bigstruts argument.
- % This will be close, but probably not exact; you can use the fixup argument
- % to refine the result. (If you do this repeatedly, you'll probably want to
- % wrap these steps up in a simple macro. Note that the modified \bigstrutjot
- % value will not give reasonable results if you have bigstruts and use this
- % argument for its intended purpose elsewhere. In that case, you might want
- % to set it locally.)
- %
- % If you use \multirow with the colortbl package you have to take
- % precautions if you want to color the column that has the \multirow in it.
- % colortbl works by coloring each cell separately. So if you use \multirow
- % with a positive nrows value, colortbl will first color the top cell, then
- % \multirow will typeset nrows cells starting with this cell, and later
- % colortbl will color the other cells, effectively hiding the text in that
- % area. This can be solved by putting the \multirow is the last row with a
- % negative nrows value.
- % Example:
- %
- % \begin{tabular}{l>{\columncolor{yellow}}l}
- % aaaa & \\
- % cccc & \\
- % dddd & \multirow{-3}*{bbbb}\\
