overflow: hidden not working with FixedColumns

greenflash

If I use FixedColums with two fixed columns on the left hand side, overflow: hidden seems to have no effect on the td cells in the fixed columns. The whole of the left hand sub-table is hidden, but the sub-table itself does not get rendered as you'd expect: all I can see is the first column.

You can see this effect on the demo page for two fixed columns at http://www.datatables.net/release-datatables/extras/FixedColumns/two_columns.html

If I use Firebug to edit the text in a , eg change "Gecko" to "Geckoxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" and add the properties overflow: hidden and white-space: nowrap, all I see is the Rendering Engine column and not the body for the Browser column.

Any ideas?
