regarding dropdown list and tables

hi

in my application i have a dropdown list with values list1, list2, list3 and so on

when i select list1, then a Table1 will be displayed with Add,Delete,Modify butons. when we push Add button another form will be displayed and after filling the form the data will be added in the Table1 and the same for modify and delete buttons. Till this step i did using ComponentController binding .it works fine now my doubt is that for one table i used one component controller and what the remaining Table2, Table3 when i select list2, list3.What i performed in the Table1, i need to perform the same operations in Table2, Table3. For this should i go for three Component Controllers and if that is the case how should i map these component controllers

Thanks
