Don't know how to do what? You listed some source code without any

To get help, you need to be specific. Did the code compile? Did it do what
you expected?
Here I repeat, from my previous post, what I want to do,
because some people apparently CAN'T read:
I would like MASortableTable to extend only JTable
(eg.
class MASortableTable extends JTable
{
public MASortableTable(sorter)
{
super(sorter);
setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
sorter.addMouseListenerToHeaderInTable(this);
} // MASortableTable()
....
} ),
but don't know how to do it.
Here is the whole class MASortableTable,
comments are in Polish.
