   public InputAbook2(){

    setLayout(new GridBagLayout());
    JLabel lName = new JLabel("First Name");

    InButton.setMnemonic('I');
    InButton.addActionListener(new InButtonListener());

          FieldName.setText("");
          FieldLastName.setText("");
          FieldAddress.setText("");
          FieldPhNum.setText("");
          TAreaNotes.setText("");
          FieldName.requestFocus();
        }
      });



  GridBagConstraints pos = new GridBagConstraints();
  pos.anchor = GridBagConstraints.WEST;

  pos.gridx = 1;

    }
}

Have a look at AbstractTableModel.fireTableStructureChanged()
