Feature request: Scrollable table body with fixed header

Created by: bigblockla

Hey,

Recently I've been putting together a page that has a lot of data. I'd like to consolidate this more by adding a scrollable feature to my table, however, overflowing the table in y with a max height causes the header to scroll. I've tried several CSS tricks and looked all over the internet for a solution. Most people suggest turning tbody into a block element, however this messes up all of the column formatting.

Having the ability to do something similar to <table class="table table-bordered table-scroll table-fixed-header" .... would be awesome.
