# bug in tabu when rowcolors are defined?

In the following code the vertical separation from cell to the bottom is negative instead of the defined \tabulinesep=5pt when \rowcolor{headcolor} and and \rowfont are defined.

\documentclass[]{scrartcl}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage[utf8]{inputenc}
\usepackage[table]{xcolor}
\usepackage{tabu}
\tabulinesep=5pt
\listfiles
\begin{document}
\begin{tabu} to 0.8\textwidth{X[1,L]X[1,L]}
\hline
\rowfont[l]{\bfseries}%
\hline
text which is considerably longer than the width of the column &
text which is considerably longer than the width of the column \\
\hline
\end{tabu}
\end{document}


Here the visual result

Is this a bug in the tabu package? I contacted the author of tabu, but got no answer in the last days.

\rowcolor is defined by colortbl. So it's an incompatibility between the two packages. You can fix that by using the tabu command \taburowcolors instead:

\colorlet{headcolor}{gray!25}
\begin{tabu} to 0.8\textwidth{X[1,L]X[1,L]}
\hline

Ok, but that is a different command with a different usage. It can be used to implement the same colors with a different approach. So in my example \rowcolor is showing a bug in tabu environments. – Matthias Pospiech Nov 25 '11 at 8:24
Unfortunately, that does not work with \multicolumn :-( – Frederick Nord Feb 14 '13 at 15:40
