Define Table Name (whit diferent indexes)

Hello
In my case i generate correctly many tables with an iterator (the same table with diferent content).
Now, to modify later with PERL (i have to add rows at the end of page) i need to recognize the diferent tablenames, but every same table have the same name!!! (i use grep to search table name in content.xml)
I need to lnow how to set diferent table names adding the 'index' like this:

-Table1_0 for first set
-Table1_1 for second set
-Table1_2 for thirst set
-Table1_3 for fourth set

Thanks!
