Convenience function that inserts a new column into the gtk.TreeView
with the given cell renderer and a GtkTreeCellDataFunc to set cell renderer
attributes (normally using data from the model). See also
TreeView.columnSetCellDataFunc, TreeView.columnPackStart.
If tree_view has “fixed_height” mode enabled, then the new column will have its
“sizing” property set to be GTK_TREE_VIEW_COLUMN_FIXED.
