So let me explain, I want to use the header as in the example http://livedemo.exadel.com/richfaces-demo/richfaces/dataTable.jsf?c=dataTable&tab=usage and freeze some columns as in the example http://livedemo.exadel.com/richfaces-demo/richfaces/scrollableDataTable.jsf?c=scrollableDataTable&tab=usage.
Any Idea?
