How do I change the order of columns in a table? I have too many rows and doing this manually would be a horrible pain.
A MWE to get us going (let's get rid of Yoda!):
\documentclass{article}
\begin{document}
\begin{table}
\begin{tabular}{c c c c}
\hline \hline
this & in & order & is \\ \hline\hline
1 & 3 & 4 & 2 \\
a & c & d & b \\
\hline
\end{tabular}
\end{table}
\end{document}
