class name overlap when mouse hover in latest https://doc-snapshots.qt.io/qt6-dev/classes.html

After this issue https://bugreports.qt.io/browse/QTBUG-101667, it seems that it does not fix the issue perfectly.

After the fixing, we can not see the full class name at first glance, have to do mouse hover event. But even after doing mouse hover, it still has some level class-name overlap

suggest to set the column length according to the longest class name
