Yes, but that column includes a few pixels of white space on the left of
the checkbox and a few pixels of space (including the space the "active"
rectangle takes) to the checkbox's right. At least I could not find a way
to work around this without having to try something rather fancy with
absolute screen coordinates which I thought would not be worth the effort
and besides bear potential for bugs.

To learn about the difference between the ttk.Treeview and the tktreectrl
widget I would like to be able to point you to their web page, but
unfortunately sf still appears to be in service. There is an archived
page available at:
https://web.archive.org/web/20170301130644/http://tktreectrl.sourceforge.net/
Just look at the screenshots and you will get an idea about how much more
capable this widget is than the ttk Treeview.
The difference between the two links is, that *tktreectrl* is the tk
extension library (written in C, windows binaries are available on the sf
download site, linux binaries included in most recent distributions) and
*tkintertreectrl* is a Python wrapper module I wrote for it (both
Python2 and -3). The docs on sf are of course currently down with the rest
of their pages, but are included in the download, plus a few very simple
demos. In case of questions you can always ask me :)

I guess I could answer what you asked there :)
The last release was made in 2008. I bet it still works :)

Kevin Walzer's python wrapper for tablelist is available here:
https://web.archive.org/web/20150920011432/http://tkinter.unpythonic.net/wiki/TableListWrapper
Looks like Python2 only, but it shouldn't be a problem to adapt it to
Python3. Personally I never used it, but I have been hearing good things
about it. I think Kevin probably still reads the list, so if you ask
questions about it here there might be a good chance to get help.

There is actually excellent documentation about Pmw on their page and
will hopefully soon be available again once sf have restored their
content. Probably downloads will still work, and they include the
documentation. However, unless something new showed up recently there is
no multi colomn listbox widget with icon support included.

Seems like right now we are learning something about the bad side effects
of monopoly structures... :)

Probably the pydoc documentation is of more help. Or just look into
tix.py :)
Tix itself comes with a number of tcl demos, which maybe give you
an impression.

Agreed :)
