So wat i m trying to do is ,i want a table whose columnwill be the attributes of the amount Slab .And there will be n such rows for Amount Slab.

Can anybody tell me haw can i implement this as i dont know how many records the user will add.So i dont no the no:of rows(initially).And i shd be able to modify ,delete and add the rows to the table at run time.and on the add click tha records from the table shd go to the web service.

Can anybody tell me how to get the data from a table.
