For RTL orientation [`getCellRect`](https://github.com/openjdk/jdk/blob/6c5e15c1a291ca5ba1e4c3a90351bc71665ce988/src/java.desktop/share/classes/javax/swing/JTable.java#L2977)  returns position excluding the Offset meaning the gap between panel x till x position of table which is x position of first column.  So instead of modifying at JTable class, I am updating here.
