Did you know...
...that you can group columns/rows in JGoodies FormLayout.
Columns/rows in a group will all get the same size.
JFormDesigner displays a line connecting the grouped columns/rows.
Select the columns/rows you want to group in the header and
select Group from the popup menu.
To remove a column/row from a group, select it and select Ungroup
from the popup menu.
You can extend existing groups by selecting at least one
column/row of the existing group and the columns/rows that you want to add
to that group, then select Group from the popup menu.
