help wanted
Description
If there are amount of complex data in datatable, I think the following two features will be very helpful.
- An option to show header both on top and bottom.
- Make header on top fixed when user scrolls down. (like this one: http://legacy.datatables.net/extras/fixedheader/)
Both of the features can avoid showing double vertical scrollbars and make users know the title of each column. (browser scrollbar and datatable scrollbar)
