QTableView::resizeColumnToContents : possibility to resize the entire table by default

Hi.

In the current version, the user has to reimplement sizeHintForColumn() in order to have the "intuitive" resizing behaviour that is resizing the whole table.
It would be far more easier and intuitive to add this option by default, because when you initialize a table with data, you want (in general) to resize the whole content and not just the visible one.

Thank you.
