Tktreectrl has a built-in feature that does exactly what you describe.
However to make it really functional it requires some extra tweaking by
the programmer and it is also relativeley slow. Obviously it is designed
for occasional use , e.g. explorer-alike file renaming in a directory
listing.

To add this from scratch for the ttk.Treeview and building a spreadsheet
from it will probably be quite a lot of work for a relatively poor result.
For a very simple spreadsheet widget that comes with the standard library
the Tix.Grid seems to be the widget of choice. If this is not capable
enough I believe tktable is the best bet.

Regards

Michael
