Reimplements: QAbstractItemView::sizeHintForColumn(int column) const.

Returns the size hint for the given column's width or -1 if there is no model.

If you need to set the width of a given column to a fixed value, call QHeaderView::resizeSection() on the table's horizontal header.

If you reimplement this function in a subclass, note that the value you return will be used when resizeColumnToContents() or QHeaderView::resizeSections() is called. If a larger column width is required by either the horizontal header or the item delegate, the larger width will be used instead.

If you reimplement this function in a subclass, note that the value you return is only used when resizeRowToContents() is called. In that case, if a larger row height is required by either the vertical header or the item delegate, that width will be used instead.
