Thanks MC I tried doing it, But I call very large chunk of data and that too call it from servlet each time dynamically from db. Making two datatable will make processesing heavy and cross checking and rearranging tables each time a user clicks table to sort will make it worse. Will there be a fix for it in future at api level itself? Should i try some other way round for it?
