Since "different types of data" must be loaded to the JTable, you need different AbstractTableModels. myModelA, myModelB, myModelC etc.

You can set the appropriate model with:

  myTable.setModel(new myModelA());

and

  myTable.setModel(new myModelB());

etc, at the ActionListener - actionPerformed() of your buttons. Each model will provide headings for the appropriate data.
