Graphics, Figures & Tables ⇒ Line on top cells

[bstex]

Hi,
I have made this table:

with this code:

Code: Select all

\documentclass[11pt,a4paper]{book}

\usepackage[table]{xcolor}

\begin{document}

\begin{table}
\centering\arrayrulecolor{black}
\begin{tabular}{l|ccccc|}
\cline{2-6}
\rowcolor{red}\multicolumn{1}{c|}{\cellcolor{white}A} & B & C & D & E & F \\ \hline
\multicolumn{1}{|l|}{G}  & H & I & J  &   K   & L  \\ \hline
\multicolumn{1}{|l|}{M}  &  N & O  & P & Q & R  \\ \hline
\multicolumn{1}{|l|}{S}  &  T  & U &  V & W & X    \\ \hline
\end{tabular}
\end{table}

\end{document}

but the cline on the top of the table is not visible?
How can I make it visible?
Thank you.

This shifts the line a bit up to make it visible:

\cline{2-6}\noalign{\vskip.3pt}

I still can't believe that I had to MOVE the line just to make it be seen.
Come on, LaTeX does billion of things, it cannot make a line to be seen over a colorful cell?
Thank you very much for the solution, Stefan.

The line is drawn first, the colour added on top of it.

Something many users trip over.

I'm fine with the solution you provided, Stefan and thank you again.
I just want to add this:
I was trying to manage making the cline be seen with transparent colors, but I couldn't make it. I thought that if the background of the red cells was transparent, maybe the cline would be visible.
Is it possible?

[Stefan Kottwitz]

I think the normal color support does not work with transparency. But TikZ does. So one could create a table using TikZ, with transparent colors, see here for example:

• Fancy tables with TikZ
• Colorful tables with TikZ

TikZ can be used with layers. So it is possible, to have all table lines on the foreground layer, and the color filling on the background layer.

Cool. I'll play with it and post if I find a solution.
Thank you.
