Hi,
if it's one/two columns only: use complex cell content:
Code:
GRIDCOL
PANE
ROW
LABEL height="100%" width="100%"
LABEL height="100%" width="100%" renderd=".{rightColRendered}"
In your program: control the rendering of the right LABEL accordingly. So you have some kind of "speudo-merging" ;-).
If it's much more than this: check the REPEAT component for completely individual arrangement of controls.
