[texhax] Conditionally Formatting Tabular Cells

[Mike B.]

Dear All,

Is it possible to format groups of tabular cells?.
I have a tabular with several rows and columns and I wish to modify the formatting (for example, to \tt) for groups of cells (not an entire row or column).  There may several such groups inside the tabular so manually entering the formatting commands for each cell seems tedious.

So basically I am looking for a way to conditionally format tabular cells, so a meta-code is something like
if row==1:2 and column==1:3 \tt
if row==5:7 and column==6:7 \tt

to change two groups of cells to \tt.

Thanks,
Mike.
