Removing the CellTable Margin

By default, the CellTable is surrounded with a border. To remove it, customize the generated gap class:

protected void configureObjectMetaDataById(int ID, Object object) {
		super.configureObjectMetaDataById(ID, object);
		switch (ID) {
		case LAYOUTMANAGER:
			LayoutManager locallayoutManager = (LayoutManager) object;
			//remove margin for cell table
			locallayoutManager.setMarginWidth(0);
			locallayoutManager.setMarginHeight(0);
			break;
		default:
			break;
		}
	}
