Description

When removing all the rows of a WStandardItemModel inside a WTableView using WStandardItemModel::removeRows(), the WTableView does not remove the columns it already has. However, when a new row is added, using WStandardItemModel::appendRow(), all the column in the new row are added as new column instead of reusing the existing ones.

This is likely an issue with WTableView as setting the same WStandardItemModel using WTableView::setModel() solves the issue.
