FixedColumns example - individual column filtering

# Preamble

This example shows a fairly complex example of FixedColumns in action. Primarily it shows how multiple rows can be used in the THEAD or TFOOT element of the table such that you can provide extra information. In this case it shows how a column filter could be implemented.
