Using array m{} to vertically align cells in a tabular, and changing row height with \\[] the last cell is not properly aligned:
\documentclass{article}
\usepackage{array}
\begin{document}
\begin{tabular}{|m{.3\linewidth}|m{.3\linewidth}|m{.3\linewidth}|}
\hline
A & B & C \\[1cm]
\hline
1 & 2 & 3 \\[2cm]
\hline
\end{tabular}
\end{document}
Can't understand why. Any idea?
