Just for clarification, the "weird behaviour" is that it seems as if the
QTable loses cursor focus, and I cant edit a cell unless I double-click on
I just saw a setCurrentCell() method, I'll try that instead of editCell()
If I want to reference a column, where do I start counting?
The column numbers doesn't seem to start at 0 or 1.
