You can also use munger to change part of the name of a column. This is useful after "tabulate" or "summary" specially if you iterate through the different variables.
eg one variable
column(data_table,2)<<set name(munger(munger(eval(char(column(data_table,2))),1,"Column(\!"text_that_you_want_to_change ",""),1,")\!")",""));
eg all variables
for(i=1,i<=n col(data_table),i++,
column(data_table,i)<<set name(munger(munger(eval(char(column(data_table,i))),1,"Column(\!"text_that_you_want_to_change ",""),1,")\!")","")));
