# How to color the font of a single row in a table?

I have a table and I want to make the font color red for just one row (not the background). How do I do that? Here's my table:

  \begin{tabular}{ l | l l l l }
& 1 & 2 & 3 & 4 \\
\hline
1   & A & B & C & D \\
2   & A & B & C & D \\
3   & A & B & C & D \\
4   & A & B & C & D \\
\end{tabular}

You could use the tabu environment of the tabu package with the command \rowfont, for example:

\documentclass{article}
\usepackage{tabu}
\usepackage{xcolor}
\begin{document}
\begin{tabu}{ l | l l l l }
\rowfont{\color{red}}
& 1 & 2 & 3 & 4 \\
\hline
1   & A & B & C & D \\
2   & A & B & C & D \\
3   & A & B & C & D \\
4   & A & B & C & D \\
\end{tabu}
\end{document}

Much better than my idea of a per-column \color{red}. –  Werner Aug 23 '11 at 17:52
Is an unaltered tabu environment equivalent to an unaltered tabular environment? –  doncherry Aug 23 '11 at 17:58
@doncherry: unaltered it behaves very similarly. Differences are explained in the manual, there's a section dedicated to it. –  Stefan Kottwitz Aug 23 '11 at 19:10
@Eddy: don't worry, installation is not hard, and by trying that you will get further knowledge. You can download it from CTAN, and see How do I install a dtx file, Placing sty files and if you use TeX Live (not Xubuntu repositories) Installing tabu.sty. –  Stefan Kottwitz Aug 23 '11 at 20:24
Figured out how to do it: 1. Download tabu.dtx and tabu.ins 2. run latex tabu.ins 3. move tabu.sty to $HOME/texmf/tex/latex/commonfiles 4. run texhash$HOME/texmf –  Eddy Aug 28 '11 at 11:49

If you don't want to use the tabu package you can define a \rowstyle command together with supporting column types + and = as follows:

\documentclass{article}

\usepackage{array}
\usepackage{xcolor}

\makeatletter

\newcommand*{\@rowstyle}{}

\newcommand*{\rowstyle}[1]{% sets the style of the next row
\gdef\@rowstyle{#1}%
\@rowstyle\ignorespaces%
}

\newcolumntype{=}{% resets the row style
>{\gdef\@rowstyle{}}%
}

\newcolumntype{+}{% adds the current row style to the next column
>{\@rowstyle}%
}

\makeatother

\begin{document}

\begin{tabular}{ =l | +l +l +l +l }
\rowstyle{\color{red}}
& 1 & 2 & 3 & 4 \\
\hline
1   & A & B & C & D \\
2   & A & B & C & D \\
3   & A & B & C & D \\
4   & A & B & C & D \\
\end{tabular}

\end{document}
