<h3>How to change a whole row of a table</h3>
<p>Each cell of a table is set in a box, so that a change of font style
(or whatever) only lasts to the end of the cell. If one has a
many-celled table, or a long one which needs lots of rows emphasising,
putting a font style change command in every cell will be impossibly
tedious.
<p>With the <i>array</i> package, you can define column modifiers
which will change the font style for a whole <em>column</em>. However,
with a bit of subtlety, one can make such modifiers affect rows rather
than columns. So, we set things up by:
<blockquote>
<pre>
\usepackage{array}
\newcolumntype{$}{>{\global\let\currentrowstyle\relax}}
\newcolumntype{^}{>{\currentrowstyle}}
\newcommand{\rowstyle}[1]{\gdef\currentrowstyle{#1}%
#1\ignorespaces
}
</pre>
</blockquote>
Now, we put '<code>$</code>' before the first column specifier; and we put '<code>^</code>'
before the modifiers of subsequent ones. We then use <code>\</code><code>rowstyle</code> at
the start of each row we want to modify:
<blockquote>
<pre>
\begin{tabular}{|$l|^l|^l|} \hline
\rowstyle{\bfseries}
Heading & Big and & Bold \\ \hline
Meek & mild & entry \\
Meek & mild & entry \\
\rowstyle{\itshape}
Strange & and & italic \\
Meek & mild & entry \\ \hline
\end{tabular}
</pre>
</blockquote>
The <i>array</i> package works with several other
<code>tabular</code>-like environments from other packages (for
example <code>longtable</code>), but unfortunately this trick won't
always work.
