The problem with \arraystretch is that the formula does not appear
centered (vertically) in the cell, so if you want the bottom line of the
cell not to contact the bottom of the formula, then you get allot of
space in the top.
I think I'm not very clear (my English does no allow for more) so may be
the best thing is again a little example:
