When using \rowcolors to alternate row coloring, some vertical lines are missing in the restulting table.
\documentclass{scrreprt}
\usepackage[table]{xcolor}
\begin{document}
\begin{table}
\rowcolors{2}{gray!25}{white}
\begin{tabular}{l|ccc|cc|ccc|}
& A & B & C & D & E & F & G & H \\\hline
Verfahren & p & a & p & a & a & a & a & a \\
Verfahren & p & a & p & a & a & a & a & a \\
Verfahren & p & a & p & a & a & a & a & a \\
Verfahren & p & a & p & a & a & a & a & a \\
\end{tabular}
\end{table}
\end{document}

If I manually insert \rowcolor{gray!25} for every other row, the lines are correct for the "white" rows (since they are not explicitly set to to white as in the \rowcolors case)
Am I missing something?
