Table Filter - Specifying columns to filter

Hi All,

I am using the TableFilter class from http://wiki.scn.sap.com/wiki/pages/viewpage.action?pageId=341542375

and  http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/e0cf0997-2e08-2d10-b08e-964a2c04c47a?overridelayout=true.

In page 21 in states - "You can specify which columns can have a filter, instead of letting the class choose all columns that it can handle".

How can I achieve this?

Thanks,

Aviad
