To write the solution of an exercise, i want to fill in the tabular with the answers in red. The headlines of the table should stay in the same style than the exercise and only a part of the table should be colorized. I can achieve that by using \textcolor{red}{...} in each cell of my table but it's pretty brutal. I'm looking for a solution to declare that all the following words must be in red untill the end of the environment tabular.
I've tried some \color{red} but it doesn't work.
Here is a small example.
\documentclass[11pt,a4paper]{report}\usepackage[utf8]{inputenc}\usepackage[left=1.00cm, right=1.00cm, top=1.00cm, bottom=1.00cm]{geometry}\usepackage{colortbl}\usepackage{chemformula}\begin{document} \begin{center} \footnotesize \renewcommand{\arraystretch}{1.5} \hspace*{-1cm}\begin{tabular}{|c|c|c||c|c|c|c|c|c|c|c|} \hline \rowcolor{black} \multicolumn{11}{|c|}{\textcolor{white}{Corps purs}}\\\hline \rowcolor{gray!90}élémentaires& \multicolumn{2}{c||}{simples} & \multicolumn{8}{c|}{composés}\\ \hline \rowcolor{gray!70}&métal.& non-métal. & \multicolumn{2}{c|}{Oxydes} & Hydroxydes & \multicolumn{2}{c|}{Acides} & \multicolumn{2}{c|}{Sels} & Corps organiques\\ \hline \rowcolor{gray!50}&& & métal. & non-métal. & & bin. & tern. & bin. & tern. &\\ \hline && & & & & & & & &\ch{C6H12O6}\\ \hline && \ch{Fe2O3} & & & & & & & &\\ \hline && & & & & & & & &\\ \hline&& & & & & & & & &\\ \hline&& & & & & & & & &\\ \hline&& & & & & & & & &\\ \hline \end{tabular} \end{center}\end{document}Desired output :

PS : i'm aware that Fe2O3 is at the wrong place, it was only for a second element :) !
