In native the actions are extended to end of selected columns cells either LEFT/RIGHT but in swing gtk look and feel the selection is extended to one cell to left/right. This might be taken as reference of Windows OS since the same is observed in Windows native. Hence I have update the actions for Ctrl Shift RIGHT & LEFT.
