This is a pure javascript solution to make a standard table component scrollable both horizontally and vertically with fixed headers. Simply drop it on a page and supply the ID of your table and a either a pixel height or a height percentage. Remove any paging, set your MaxRecords to infinity+1, and scroll away.

You can also supply options to specify horizontal and vertical scrollability as well as a comma-delimited string to specify column widths. 

This was designed for reactive web and has not been tested with mobile.
