If you call WTableView::setColumnHidden before the table has been
rendered, e.g. right after constructing the WTableView, the application
will crash because the widgets for the header have not yet been created
and an out-of-bounds error occurs.
I have attached a patch that fixes the problem for me.
In future, is this the best way to submit patches, or is there a more
official route?
