Without variable names or anything it is a bit awkward to provide much detail. The ALL instruction will create sub totals.
proc tabulate data=sashelp.class;
class sex age;
var height ;
tables sex *( age All='total'),
height*sum;
run;
Notice that the ALL with with the subgroup Age to get a total within the values of Sex.
If also want a grand total:
proc tabulate data=sashelp.class;
class sex age;
var height ;
tables (sex all='Grand Total') *( age All='total'),
height*sum;
run;
In Tabulate the All instruction may only be used with Class variables.
Another approach uses multilabel formats but this may get you started.
As for output to different sheets, that is your choice and may depend on the method you use to get it into Excel.
