unable to click a cell in qt table widget

I'm unable to click a cell using the row/column names, nor indices.  I can get the rowCount and columnCount of the table.  So, it seems test complete is able to access the widget, but that's about it.  I've tried several other properties and methods, but only wRowCount and wColumnCount seem to work.  



The test crashes if I try to clickCell a specific cell.  



Thoughts?
