# Why tabular doesn't work with ModernCV

When I try to insert a tabular in my CV using modernCV document like this

 \begin{tabular}{|c|c|c|}
\hline aa & bb & cc \\
\hline dd & ee & ff \\
\hline
\end{tabular}


I don't get any border. It appears that it's not possible to make a tabular in a moderncv. How can I solve this?

In order for rules in tabular to appear, each document class has to define a positive value for \arrayrulewidth and moderncv either doesn't assign a value or it sets it to 0pt; something similar happens to \tabcolsep; simply assign the standard values for those lengths:

\documentclass{moderncv}

\firstname{A}
\familyname{B}

\setlength\arrayrulewidth{.4pt}
\setlength\tabcolsep{6pt}

\begin{document}

\begin{tabular}{|c|c|c|}
\hline aa & bb & cc \\
\hline dd & ee & ff \\
\hline
\end{tabular}

\end{document}


In fact, there was an attempt to set these lengths (and some others) in moderncv.cls, but the author decided they were not required; one can see

% not required
%\setlength\arraycolsep{5\p@}
%\setlength\tabcolsep{6\p@}
%\setlength\arrayrulewidth{.4\p@}
%\setlength\doublerulesep{2\p@}
%\setlength\tabbingsep{\labelsep}


in moderncv.cls.

As a personal suggestion, consider removing vertical rules from your tables and using the booktabs package.
