some action should perform

what kind of action?

you can add mousemotionlistener table , handle mousemoved(...) event:

point previouscell = new point(-1, -1);  @override public void mousemoved(mouseevent e) {     jtable table = (jtable)e.getsource();     int row = rowatpoint(e.getpoint());     int column = columnatpoint(e.getpoint());     point currentcell = new point(row, column);      if (currentcell != previouscell)     {         //do         previouscell = currentcell;     } }
