LyX - Highlight a result in table without using ERT

Question

I created a table in Lyx and I would like to put a square around a column to highlight the results without using the ERT command. Is that possible? I found that \colortbl and \mystrut can be useful but I don't see how to implement them. Thanks a lot for any help!

Answer 1

Here is a simple solution with pstricks: I define a node at the top of the column, another node at the bottom, and I connect them with a \ncbox command. The width of the box is automatically calculated thanks to the eqparbox package: top node and bottom node use a system of tags which is used to compute the largest node. Note you have to use the --enable-write18 switch for pdflatex, if the distribution is MiKTeX, --shell-escape if it is TeX Live. Alternatively, you can compile with xelatex

\documentclass[a4paper, x11names]{article}
\usepackage{array}
\usepackage{eqparbox} 
\usepackage{pst-node}
\usepackage{auto-pst-pdf}
\newlength\boxsize

\begin{document}

\begin{postscript}
\renewcommand\arraystretch{1.5}
\begin{tabular}{lcccc} 
\hline \hline
 & {\small{}Mean} & \Rnode{T}{\eqmakebox[H]{\small{}St. Dev.}} & {\small{}Min} & {\small{}Max}\\
  \hline \hline \hline
  Blah & Blah & \Rnode{B}{\eqmakebox[H]{Blah}} & Blah & Blah \\[-5ex]
  \tabularnewline 
  \end{tabular}
\setlength{\boxsize}{\dimexpr\eqboxwidth{H}/2+\fboxsep\relax}
 \ncbox[linecolor=PaleVioletRed3, boxsize=\boxsize, nodesep=4pt]{T}{B}
\end{postscript}

\end{document}
