# How to change line color in tabular?

How can I change the color of the lines (the frame) in a tabular environment? In the following MWE:

\begin{tabular}{c|c|c}
a&b&c \\ \hline
d&e&f \\ \hline
g&h&i
\end{tabular}

I would like the horizontal and vertical lines of the table to have, say a blue color.

You can use the colortbl package for this. It works as follows:

\documentclass{article}
\usepackage{colortbl}
\begin{document}
\begin{tabular}{l!{\color{green}\vrule}l}
\arrayrulecolor{red}\hline
test & test\\\arrayrulecolor{blue}\hline
\end{tabular}
\end{document}

Looks like this:

Or the xcolor package with the table option (internally loading colortbl and giving access to the full xcolor capacity). –  Gonzalo Medina Jan 10 '12 at 16:08
the command \arrayrulecolor{red} is exactly what i need. –  nicolas roy Jan 10 '12 at 19:09

The tabu package could also be helpful here.

\documentclass[11pt]{article}
\usepackage[T1]{fontenc}
\usepackage{xcolor}
\usepackage{tabu}

\begin{document}
\taburulecolor{blue}
\begin{tabu}{c|c|c}
a & b & c \\ \hline
d & e & f \\ \hline
g & h & i
\end{tabu}
\end{document}

i voted for wh1t3's solution, because, i need this in a very long document, with many tabular that are already written, and i don't want to change the environment. But the package tabu seems looks very interesting. Thank you –  nicolas roy Jan 10 '12 at 19:11
