Sorry for jumping in so late. I've been following your issue for some time.

Initially you had mentioned "...i.e. the model is not hierarchic, all
rows have the same parent (root) and consist of multiple
columns..."

In such a case, why did you choose to go for a tree based model and view combo?

If there is no hierarchy in your data (i.e it's flat) wouldn't it be
easy for you to "flat" model/view combo? (Table model/view as
Sean/Andre suggested)

I was initially confused thinking you had a tabular data for each
_level_ in your hierarchy and thats why you were using a tree
structure. But I guess thats not the case with you.
