that remains to be seen as i haven't checked out the bug report yet, but you might try using <table style="table-layout:fixed"> or table-layout:auto, or maybe setting an explicit height on the table or on each row.
ok, i see how that might be a problem and we will have to investigate it more. would you mind submitting a bug report through infragistics developer support? http://infragistics.com/gethelp
normally i would enter a bug on your behalf, but the dev team is extremely busy preparing for PDC this week. submitting bugs through developer support is to your advantage though, as they will make sure they have your issue reproduced exactly, and they will notify you when the status of the bug changes.
