Pagination issue.

sachin404

I have a 100 records in a data table and pagination size per page is 10, in a first page its displays first 10 record that is 1 to 10 of 100. When we Navigate to 2 nd page it displays next set of record that is 11 to 20 of 100, now change the pagination size to 25, on a second page its showing 11 to 35 of 100, click on 3rd page its showing 51 to 75.
Ideally it should show 36 to 60 of 100 on 3rd page.

Please let me know how we can achieve this logic in a datable.
