Is there a way to designate a specific column in a tabular environment as "hidden" so it is not printed, or not included? Here is a MWE.
\documentclass{article}
\begin{document}
By specifying the second l in the tabular env, possibly, as D(elete), I would like to change this
\begin{tabular}{lll}
a & b & c \
d & e & f
\end{tabular}
\noindent to look like this
\begin{tabular}{ll}
a & c \
d & f
\end{tabular}
\end{document}
