Latex does not have a special construct to do that -- but see the other
replies to your question for workarounds.
If you accept the row labelling on the left rather than on the right,
there is however a TeX construct just for this problem:
X = \bordermatrix{ & n-m & m & \cr
1 & a11 & a12 \cr
2 & a21 & a22 \cr
3 & a31 & a32}
This plain tex construct still exists in latex. You can enter this using
the TeX code (evil red text) in mathmode. Of course it does not get shown
WYSIWYM on the screen.
