GGC: How to adjust the nested table columns

Hello!

I would to adjust the visible nested table column:

Grid:
(Master) ID, DESCRIPTION
(Level1) ID, DESCRIPTION
(Level2) ID, DESCRIPTION
(Level3) ID, DESCRIPTION

In all Tablels (incl. Nested Table) the same Columns are visible.

gridGroupingControl1.NestedTableGroupOptions.ShowColumnHeaders = false;
gridGroupingControl1.NestedTableGroupOptions.ShowCaptionPlusMinus = false;
gridGroupingControl1.NestedTableGroupOptions.ShowCaption = false;


Now i will to adjust the nested columns, so that right border of the 3rd Level Column ID, has the same position than the 2nd Level Column ID and so on.

And if I resize the Column Header of the Master Table, all nested Tables Columns shoud be resized to.

Please Help!!!!

Here is a try at doing this.
