I've just had a quick read of the code. 

It seems like it only works with QML ListModel type models at the moment, 
but not QAIM. ( root.model.get(rowIndex) won't work for a QAIM).

It seems like there's only one role of data possible per column, and it must 
be specified in a TableColumn element in the header property.

Does the research include plans to make it possible to use QAIM with these 
QML views, or is that considered a dead end? Does it include work to make it 
possible to make multiple roles of data available? Does it include work to 
get features from the QTableView like re-ordering columns, resizing columns, 
selecting multiple rows/items (QML has no concept of a selection model) etc? 
Does it include making new features possible like sticky columns that don't 
move when I scroll horizontally, or zooming out and in?

I'm not trying to be annoying, just trying to understand the scope of what 
you're trying to do with this stuff. Tables, trees and model-view separation 
are difficult. You might have hard work and spaghetti code ahead if you want 
to make them all available in QML.
