KivyMD is in development, it is a moving target. It looks like some class initialization changed.

It is possible that the version of KivyMD installed on your computer is not the same as the one documented.

Part of the problem is I think the documented version is the unreleased version :(

This is what you could try:

A 'pip3 list' will tell you the version you have installed.

The documented versions are listed here:

https://kivymd.readthedocs.io/en/latest/changelog/

I notice I have 1.104.2.dev0 , which is not listed there; it is an install of the 'unreleased' version from a few months ago.

You probably want the unreleased version.

The version number of an unreleased version does not change with each content change.

Alternatively, the way to see what your version of KivyMD expects is to read the source.

The 'tags' under the button showing 'master'  will allow you to select the version.

https://github.com/kivymd/KivyMD/blob/master/kivymd/uix/datatables.py

Expect this experience with software that is in development.

In the last line of the program change to: DemoApp().run()
