Currently we are doing migration from Richfaces 3 to 4. I am using rich:dataTable and I want to show the vertical scrollbar for the table body. I know we can use extended dataTable, but I think in RichFaces 4 the ExtendedDataTable is not supporting colspan and rowspan. So we moved to dataTable. So, how we can achieve the scroll bar for dataTable. Please suggest me the right approach to get this.( any examples/URLs).
