Using an empty column as a divider in a JTable

Question

I\'m trying to use an empty column as a divider between pairs of columns in a JTable. Here\'s a picture and code for what I have so far. I know I can change the

Answer 1

I kind of combined both answers: I used two tables that share one's scrollbar. This works with sorting, and it actually makes the model simpler. Tabbing doesn't matter, but comparing "A" and "B" does. I think I was trying to solve a "view" problem in the "model". I made this a separate answer, because I'd appreciate any critical comments.

public TablePanel() {
    this.setLayout(new GridLayout(1, 0, 8, 0));

    JTable tableA = new JTable(new MyModel("A"));
    tableA.setPreferredScrollableViewportSize(new Dimension(200, 400));
    final JScrollPane jspA = new JScrollPane(tableA);
    jspA.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_NEVER);
    this.add(jspA);

    JTable tableB = new JTable(new MyModel("B"));
    tableB.setPreferredScrollableViewportSize(new Dimension(200, 400));
    final JScrollPane jspB = new JScrollPane(tableB);
    jspB.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS);
    this.add(jspB);

    tableA.setSelectionModel(tableB.getSelectionModel());
    jspA.getVerticalScrollBar().setModel(jspB.getVerticalScrollBar().getModel());
}
