Vertical alignment in table: m-column, row size - problem in last column

Question

Unfortunatly, I have a problem with m-columns (array package) in tables with adjusted row height. Somehow in the last column (only there) the text is not centered vertically.

Check it out:

\documentclass{article}
\usepackage{array}

\begin{document}

\begin{tabular}{|m{0.18cm}|m{0.18cm}|m{0.18cm}|}
\hline
a & b & c  \\[2ex]
\hline
0 & 0 & 0  \\
\hline
\end{tabular}

\end{document}

Answer 1

In my opinion, it is a bug and should be reported. Tweak for the impatient: add one extra column with zero width and no padding. Remember to pre-pend \\ with & on the problematic lines!

\documentclass{article}
\usepackage{array}

\begin{document}

\begin{tabular}{|m{0.18cm}|m{0.18cm}|m{0.18cm}|@{}m{0pt}@{}}
\hline
a & b & c &\\[2ex]
\hline
0 & 0 & 0 \\
\hline
\end{tabular}

\end{document}
