I am having problem installing colortbl package.
\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage[ansinew]{inputenc}
\usepackage{delarray,colortbl}
\makeatletter
\def\endarray{\crcr \egroup \egroup\@arrayright \gdef\@preamble{}\CT@end}
\makeatother
\begin{document}
$\begin{array}({ll})
a & b \\
c & d
\end{array}$
\end{document}
