Hi guys,

I have a QTableWidget (or QTableView) with 18 columns and about 500 rows.
Now scrolling works without problems, but resizing it is painfully slow. Here is an animation showing the problem:

I tried it with both a QTableWidget and a QTableView with a custom model, no difference in the slow resizing.
Is there a way to fix this slow resizing?
