Adding a +1 here. Where I have created a “similar” treeview with tableview similarities is when viewing SQL data results.
The tree aspect, represents the sorted on column with duplicate data. For instance, say you had a model that was Firstaname, lastname, address, city, state, zipcode and country. A standard address book from CS 101 If you didn’t group, it would look like a table view. If you grouped by city you would get: City1 |- fn1 | ln1| add1 | s1 | z1 | country1 |- fn2 | ln2| add2 | s2 | z2 | country2 |- fn3 | ln3| add3 | s3 | z3 | country3 City2 |- fn1 | ln1| add1 | s1 | z1 | country1 |- fn2 | ln2| add2 | s2 | z2 | country2 |- fn3 | ln3| add3 | s3 | z3 | country3 Etc etc etc My ideal view, basically looked like a tree but when expanded the rows under the parent node simply looked like a tree view. I got it mostly working, however I was never really happy with the look of it, it just looked like a treeview with an attempt to get the rows to look like a table. Just my 2 bits.

QTreeView already sort of does that, although badly. Basically, a header makes it look like a table, but it is also a tree. That is why I think the feature request is valid. It should either not have a header or header formatting for this, and then you can argue body formatting is moot, or if it has header and header formatting, then the body formatting ought to be consistent. Just googled an image: https://docs.unity3d.com/uploads/Main/TreeViewAPI-0.png (Unity, fairly common software) They say "multiple columns". As far as I am concerned, a QTreeView is a special QTableView. You can see on the above image that it is column and row based and as a direct consequence, you have "cells" of data. It is just that the tree visual expand into the first column a bit more due to its graphical nature, but it eventually is column-based.
