It's difficult to know exactly why this is without more context. Calling
the application's processEvents() method should give the user interface the
chance to update itself, but perhaps you need to explicitly call update()
on the QTableView or QTableWidget instance to ensure that it is refreshed.

An alternative way to do this is to use a timer to update the table every
two seconds.
