<title>UK TeX FAQ -- question label slashbox</title>
</head><body>
<h3>Diagonal separation in corner cells of tables</h3>
<p>You want to label both the top or bottom row and the left- or
rightmost column, somewhere at the corner of the table where the row
and column meet. A simple way to achieve the result is to construct
the table with an arrangement of rules (and possibly <code>\</code><code>multicolumn</code>
entries), to look like:
<blockquote>
<pre>
-----------------
x y
--------------
1 2 3 4 5
-----------------
1
2
3
4
5
-----------------
</pre>
</blockquote>
However, this doesn't satisfy everyone: many want the labelling in a
single cell at the top left of the table. It sounds a simple enough
requirement, yet it calls for some slightly tricky LaTeX coding.
The <i>slashbox</i> package does the job for you: it defines
commands <code>\</code><code>slashbox</code> and <code>\</code><code>backslashbox</code>, each taking the two
labels as arguments. It draws a picture with the two labels on either
side of a slanting line; the command (and hence the picture) may be
placed in the corner cell, where the labelled row and column meet.
<p>Documentation of <i>slashbox</i> is less than satisfactory: a
LaTeX source file of rather startling starkness accompanies the
package file in the distribution. It does, however, process to a
DVI file that gives some idea of how the <code>\</code><code>slashbox</code> may be
expected to look.
