Taxonomy Matrix

Hello everybody!

I'm not a newbie ;) but I'm stuck with a problem, which I thought to be easy to solve with drupal.

I want to use a 2D-Taxonomy and to display it in a table-like (matrix) view, like:

This means, there should be a first hierarchy level A/B/C, with each having a 1/2/3 subhierarchy.

x,y,z would be nodes, with the respective Taxonomy-Terms (most likely chosen as a checkbox in such a table).

I can only find modules, displaying hierarchical taxonomys as tree-menus etc..

Is there any option out there, to get a view arranged in this way?

Any help would be very much appreciated,
