Problem with \rowcolor and monochrome option

Question

I have a document that I wish to distribute both in color and monochrome. It contains tables and makes use of colored rows. Problem is, when I use the monochrome option for the xcolor package the colored rows show up as completely black and thus cannot be read.

What I would like is for the text to be readable even when the monochrome option is active.

Here is a minimal example :

\documentclass{article}

\usepackage[monochrome]{xcolor}
\usepackage{colortbl}

\begin{document}
\begin{tabular}{cc}
This & that\\
\rowcolor{yellow} This & that
\end{tabular}

\end{document}

(If I remove the monochrome option all is well).

Answer 1

Add

\makeatletter
\let\CT@@do@color\relax
\makeatother

after loading colortbl (redefining the internal command rather than \rowcolor means that you stop all colortbl color commands including use of optional arguments etc.
