FixedHeader Columns struggle with layout in IE

Hi,

I use a table wtih drilldown (first tree columns) where i want to freez the first tree columns. The fixedheader itself is working, but it seems to struggle with the layout and functioallity.

The issues are:

Tableheader is less high in fixed columns (contains some merged cells and two rows) the merged cells in the drilldown (mergend one, two or three cells) destroy the fixed layout - freezes more then the first tree columns column widths change while scrolling right (not scrolled, scrolled difference)

This I guess are all HTML issues, but I guess MS is able to handle a currect display at least in their own product MSIE.

Are there fixes on the way ? Or a recomendation which properties to set to get a correct layout ?
