Color merged and regular cells in a table individually

Question

In a LaTeX table with merged cells, how can I color each cell with a different color?

\usepackage[table]{xcolor}
...   
\begin{tabular}{...}
\cellcolor{blue} foo & \cellcolor{red} bar\\

...

There is also a command for coloring whole columns and rows.

Put \usepackage[table]{xcolor} in the preamble, use nested tables & these commands:

\rowcolor{}, \columncolor{}

Will this work well on merged cells? – denilw Jan 13 '11 at 18:59
@denilw: I don't use merged cells. I use nested tables instead. – Display Name Jan 14 '11 at 00:43

Hi @xport,that is an interesting idea, could you provide an example of how to do my example with nested tables, and include the colouring? – denilw Jan 15 '11 at 20:18

With {NiceTabular} of nicematrix, you can do that table easily and color easily cells and also merged cells with a perfect result in the PDF viewers.

\documentclass{article}
\usepackage[table]{xcolor}
\usepackage{nicematrix}
\begin{document}
\begin{NiceTabular}{cccc}[hvlines,corners=NW,colortbl-like]
          &         & \Block[fill=red!15]{1-2}{Overexpression} \
          &         & Cancer & Control \
\Block[fill=red!15]{2-1}{}%
Marked    & Cancer  & 45  & 61 \
Cell Line & Control & 42  & \cellcolor{blue!10} 52 \
\end{NiceTabular}
\end{document}

You need several compilations (because nicematrix uses PGF/Tiks nodes under the hood).
