Urgh. How do I add columns to a treeview

UltraTreeview, 10.2B03

I know that this should be simple. But it isn't, at least to this old man

I have a recursive collection of nodes, all with a name and two logical properties. I have been able to create the nodes, recursively, and show the node names in the treeview

What I want to be able to do is add the logical properties as columns so that the information is shown alongside each node.

How ? Documentation is, well, somewhat challenging

Thanks!
