GridColumn Group in java

Is it possible to keep one gridColumnGroup under another gridColumnGroup? I have been able to keep a gridColumn under a GridColumnGroup using the code below

GridColumnGroup grdInvestment = new GridColumnGroup(开发者_StackOverflowgrid, SWT.CENTER); grdInvestment.setText("Investment"); GridColumn gridColumn_2 = new GridColumn(grdInvestment, SWT.NONE);

gridColumn_2.setText("Short"); gridColumn_2.setWidth(40);

GridColumn gridColumn_3 = new GridColumn(grdInvestment, SWT.NONE);

gridColumn_3.setText("Medium"); gridColumn_3.setWidth(58);

but now i want to keep a gridColumnGroup under another gridColumnGroup. I have attached an Image and i want to use the concept of GridColumn Group to make columns just like the one in the image. In the image A,B and E are columnGroups and C,D,F and G are columns of a grid.

It looks like it's reported as a bug: https://bugs.eclipse.org/bugs/show_bug.cgi?id=240213 .
