Hi Indu,
DefaultTableTreeHeaderCellRenderer is a ULCLabel and it has to be made
opaque to be able to see its background color:
public IRendererComponent
getTableTreeCellRendererComponent(ULCTableTree
tableTree, Object value,
boolean selected, boolean hasFocus, boolean expanded,
boolean leaf, Object node) {
super.getTableTreeCellRendererComponent(tableTree, value,
selected, hasFocus, expanded, leaf, node);
this.setOpaque(true);
this.setBackground(Color.green);
return this;
}
Thanks and regards,
Janak
