Graphics, Figures & Tables ⇒ drawing boxes around sub-rectangles of a table

[lloyd22]

Hi,

Any hints on how I might accomplish this? I would like to draw boxes around subsquares of a table. For instance, in a 10 by 10 table, whose cells I identify here by column/row pairs, I want to box the rectangle whose corners encompass cells (2,3) and (7,6), then add another smaller box around (7,5) to (8,6). (The small box sits at the right of the big box, sharing one side wall, and the baselines for each are coterminal.)

Thanks!

The following code may give you some hints:

Code: Select all

\documentclass[a4paper]{article}

\newcommand\LL[1]{\multicolumn{1}{|c}{#1}}
\newcommand\RR[1]{\multicolumn{1}{c|}{#1}}
\newcommand\LR[1]{\multicolumn{1}{|c|}{#1}}

\begin{document}

\begin{tabular}{*{10}{c}}
 X & X & X & X & X & X & X & X & X & X \\
 X & X & X & X & X & X & X & X & X & X \\
