# \cellcolor overwrites table lines

I have a table which I want to fill with multiple colors, each cell possibly different from another. Which means, I can't make use of e.g. \columncolor (as in this post).

While the table without any colors looks just fine (code at the end):

...the table with one or more filled cells overwrites the table grid.

So my question is: Is there a way to, for example, redraw the grid after filling the cells or something?

\documentclass[11pt]{article}

\usepackage{color}
\usepackage{colortbl}
\usepackage{multirow}

\newlength{\Oldarrayrulewidth}
% Cline redefining to add line thickness
\newcommand{\Cline}[2]{%
\noalign{\global\setlength{\Oldarrayrulewidth}{\arrayrulewidth}}%
\noalign{\global\setlength{\arrayrulewidth}{#1}}\cline{#2}%
\noalign{\global\setlength{\arrayrulewidth}{\Oldarrayrulewidth}}
}

\definecolor{intnull}{RGB}{213,229,255}
\definecolor{inteins}{RGB}{128,179,255}
\definecolor{intzwei}{RGB}{42,127,255}
\definecolor{intdrei}{RGB}{0,85,212}
\definecolor{intvier}{RGB}{0,51,128}
\definecolor{intfunf}{RGB}{0,34,85}

\begin{document}

Please don't just post fragments of code that can not be run, always post complete small documents.

The fix should be exactly as in the other question. As documented colortbl is incompatible with \cline, you need to use \hhline instead. The fact that the cell backgrounds are different colours is irrelevant to the problem of \cline including negative spacing so that it comes under the colour.

This leads to new, but different problems: I read your documentation of the hhline package and used \hhline{*{2}{|~}*{3}{|-}|~|} instead of \Cline. Now I have white lines where no line should be. Using actual multirows has no different effect. –  Dennis Aug 2 '12 at 13:58
It might be better to solve this in a follow-up question –  Dennis Aug 2 '12 at 14:22
Just put the command \cellcolor[]{} inside brackets {} and it will not overwrite the table lines like this
\hline
