I didn't find anything via search. I have a data table that still exists in my test even though I deleted the action associated with it. How do I get rid of that thing? I've never had this problem in the past, so not sure what's going on.
to do this you need a reference to the QTP application object itself (the sheet still present also after ending your test and will be deleted permanenty...):
On Error Resume Next
Set qtp = CreateObject("QuickTest.Application")
' to add a sheet permanent to your QTP Test
' to remove such a sheet permanent from your QTP Test
Set qtp = Nothing
