colorincompatibilitytabularx
Is tabularx compatible with xcolor? I did the following:
\documentclass{memoir}
\usepackage[svgnames,hyperref,]{xcolor} % colors for hyperref
\begin{document}
\begin{tabularx}{1.00\linewidth}{X} \toprule
a
\\
b
\\
{\color{red}c} \\
d
\\
e
\\
\bottomrule
\end{tabularx}
\end{document}
But "c" is displaced so that it takes two rows. Changing the column type to l fixes it.
Is there an easy fix to making xcolor work with tabularx?
tabularx is redefining \arraybackslash (and it even tells in the docu that this is a hack:
\arraybackslash \\ hack.
\def\arraybackslash{\let\\\@arraycr}
tabu doesn't like this definition. It expect \arraybackslash to have the meaning from array.sty. So now \\ gives errors. You can give \arraybackslash locally the standard definition back:
\begingroup
\def\arraybackslash{\let\\\tabularnewline}
\begin{longtabu}
....
\end{longtabu}

May I propose to simplify your table? You do not need all these special columns in my eyes. The trick used here is to reset the row numbers which are used by the table option of xcolor. The credits for this go to Heiko Oberdiek.

Columns with column type
pandXthat is based onpare implented via a\vtop, which is a\vbox, but aligned to the top baseline.\colordoes not start a paragraph, but it creates a whatsit (\special). Because of the vertical mode, it becomes the first element in the\vtop. Also the tabular environments add struts, therefore the cells in a row have at least the height of the strut.You can avoid this by starting a paragraph:

\textcolor{red}{c}orexplicit with
\leavemode{\color{red}c}
