I want to color hline, e.g.:
\hline[color=red,width=2mm,dashed]
or something.
Below is a feeble attempt which fails. I put textcolor gray around {|} to try and make it gray. Ideally, I want it gray and dashed. Also note textcolor gray around the {\hline} tag. Any help would be appreciated using latex syntax.
Are there attributes for \hline? If so, where is the documentation?. There is a reason I love php.net for my other programing needs.
\begin{array}{c\textcolor{gray}{|}cccccccccc}
& \textcolor{gray}{P_1} & \textcolor{gray}{P_2} & \textcolor{gray}{P_3} & \textcolor{gray}{P_4} & \textcolor{gray}{P_5} & \textcolor{gray}{P_6} & \textcolor{gray}{P_7} & \textcolor{gray}{P_8} & \textcolor{gray}{P_9} & \textcolor{gray}{P_{10}}\\
\textcolor{gray}{\hline}
\textcolor{gray}{P_1} &0&0&0&0&0&0&0&0&0&0\\
\textcolor{gray}{P_2} & 0&0&0&0&0&0&0&0&0&0\\
\textcolor{gray}{P_3} &0&0&0&0&0&0&0&0&0&0\\
\textcolor{gray}{P_4} &0&1&1&0&0&0&0&0&0&0\\
\textcolor{gray}{P_5} &1&1&0&0&0&0&0&0&0&0\\
\textcolor{gray}{P_6} &0&0&0&0&0&0&0&0&0&0\\
\textcolor{gray}{P_7} &1&1&0&0&1&1&0&0&0&0\\
\textcolor{gray}{P_8} &1&0&0&1&0&1&0&0&0&0\\
\textcolor{gray}{P_9} &0&0&1&0&0&0&0&0&0&0\\
\textcolor{gray}{P_{10}} &0&0&0&0&0&1&0&1&0&0
\end{array}
First, import the color package, like so:
\usepackage{color}
And then use the arydshln package, and do this (in a tabular context):
\textcolor{gray}{\hdashline}
