One possible solution would be to use -contract- to create a 
dataset with this cross classification and their counts, and 
export it in your favorite format afterwards:

*------------- begin example -----------------
sysuse nlsw88, clear
gen marstat = married + 2*never_married
label define marstat 0 "widowed/divorced" ///
                     1 "married"          ///
                     2 "never married"  
label value marstat marstat
tab marstat
contract race marstat union, zero nomiss
list
*------------ end example -------------------

Hope this helps, 
Maarten
