Detailed Description

This proxy shows specific columns from the source model, in any order.

This allows to reorder columns, as well as not showing all of them.

The proxy supports source models that have a tree structure. It also supports editing, and propagating changes from the source model.

Showing the same source column more than once is not supported.
