Multiple Horizontal Scroll on Datatables

As far as I know, Datatables (or any other table), cannot have two horizontal scrolls. I have added Fixed Columns from Datatables and fixed up to 6 columns out of 20 or so. The first 6 columns have taken almost 70% of the table view, so on the remaining 30%, other data cannot be seen properly.

Is there any way I can add another Horizontal Scroll on the Fixed Columns (I know this beats the purpose of fixing the columns)??
