I have the following problem: I would like to use the m column type in a longtable. But if I typeset

        skdlbf & asljkdh\\

I get an error about an Illegal character in array arg in the line of \begin{longtable}{..}. If I change the m to a p, all runs well.

So why does longtable not support the m (and b) column type? Am I missing a package?
