view view pair view2
Returns a new view where the properties of each row are the union of the properties of view and view2. Each row in the returned view is created by taking the same row in view and adding onto it any different columns from the same row in view2. This means that if the same property is in both view and view2, the value from view will appear in the result.
The returned view has the same number of rows as view. If view2 has fewer rows than view, default-valued rows are assumed in view2 to generate the result. If view2 has more rows than view1, those rows do not appear in the returned view.
