How to fix the bootstrap-table header? - css

Question

I've data inside a bootstrap table. As the rows increases, the header will be out of sight on vertical scroll. So I need to fix the header of the bootstrap table with table body vertical scrollable. Also,the horizontal scroll for the whole table when columns exceed in the page.
Reference implementation without bootstrap.This is implemented by using two tables. One for header and the other for body.
I've the following data which is similar to my original data.
NOTE:I am not using any col-*-* for table's td. Because my header columns are more than 12. And may increase up to 15. So I don't use the column classes.
