This feature is planned for version 2.0

This can be difficult. Essentially you have to remove the gap from the
outer grid's border:

cellBorder.setGapSize(0);

Then you have to compensate by wrapping every other cell that is not a
nested grid in a BorderPrint with a GapBorder.

Now the hard part is the nested grids. These need to have a custom
GridLook which draws the cell border in between cells but not around the
outside perimeter of the grid. You can extend BasicGridLook to achieve
this more easily.

Thank You for your answer.

I build my grid like You say. The problem now is for the grid lines. See
the attached picture. How can I have no margin between nested grids ?

GridPrint does not yet support this. Currently the only way to do
something like this is to nest GridPrints:

+--------+------------+
| Cell 0 | +--------+ |
| | | Cell 1 | |
| | +--------+ |
| | | Cell 2 | |
| | +--------+ |
+--------+------------+
