st: relative frequency in tables

[Paolo Grillo <paolo.grillo@guest.unimi.it>]

I need to build a table with three variables (one row, a col and a 
supercol) and I would like to put in each cell the frequency, the 
relative frequency within its row and within its column of each cell, as 
it is possible in a tabulate twoway. So could you help me?
Thanks very much
