We wanted to generate a \bordermatrix (in TeX-speak) with labels
outside the brackets, something like
n
m - n ( R_11 )
n ( R_21 )
I believe that the natural size of the implied mrow in
<mtd rowspan="2"> is the height of two rows, so a stretchy operator in
there should stretch to (visually) surround the submatrix consisting of
the bottom right hand portion of the mtable.
mathplayer renders the document below as I expected, however mozilla
doesn't stretch the brackets so I get
n
m - n ( R_11 )
n R_21
with brackets only round the first row of the sub-matrix.
I think this is a mozilla bug, however whether or not it is a bug, I'd
be interested in a workaround that works in mozilla/netscape, if anyone
has any suggestions...
Our real examples have quite complicated/large expressions in the
entries so getting the labels to line up with the matrix columns seems
quite hard if they are not in the same mtable, and if they are in the
same mtable, I can't persuade mozilla to stretch the brackets...
