The number of columns in view after insertion.

Convenience function that inserts a new column into the tree view with the given cell renderer and a gtk-tree-cell-data-func callback to set cell renderer attributes (normally using data from the model). See also the functions gtk-tree-view-column-set-cell-data-func, gtk-tree-view-column-pack-start. If view has the fixed-height-mode property enabled, then the new column will have its sizing property set to be :fixed.
