Dear Experts

There is a grid with data, but I do not know the number of columns.
The columns are more than Three in every case.
Some times columns are 5 and some times 8.
The number of columns may be different every time.

I want to apply following FORMAT on Column Headers

hearheight=30
font=bold
alighnment=2

Also I want to apply following FORMAT Column 3 to last column

format=z
inputmask=99,99,999.99

The grid show data from a cursor as
thisform.grdtable.recordsource ="TRY2"

Please help
