Bug 183217 suppress duplicates leaving whitespace
I am not certain this is a bug, but if I set suppress duplicates on all the columns, I still get whitespace for suppressed rows. 2.1.2 did not do this. This issue happens in the M6 build.
engine/org.eclipse.birt.report.engine/src/org/eclipse/birt/report/engine/layout/pdf/cache/TableAreaLayout.java
rows.add( area );
		}
		else
		{
			Iterator iter = area.getChildren( );
			while(iter.hasNext( ))
			{
				ContainerArea container = (ContainerArea)iter.next();
				add(container, rows);
			}
		}
	}
	
	public void remove(TableArea table)
	{
		firstRow = true;
		ArrayList rowColloection = new ArrayList();
		add(table, rowColloection);
		Iterator iter = rows.iterator( );
		while(iter.hasNext( ))
		{
			Row row = (Row)iter.next( );
			if(rowColloection.contains( row.getArea( ) ))
			{
				iter.remove( );
			}
		}
		
		rows.resetCursor( );
	}
