Code Included: Freeze column

I attempted to modify 2 different projects on the Internet.

As you know, I have been trying to duplicate the Excel spreadsheet
freeze column capability while maintaining scrollability (vertical
across the 2 tables).

First, my problem with a modified version (added dynamically adding
rows to the 2 tables using "insert") of the code at
http://www.java2s.com/Code/Java/Swing-Components/FixedTableColumnExample.htm
produced code where the 2 tables wouldn't do exactly what I wanted.
Basically, I have been unable to get the the 2 tables to scroll
vertically together etc.

Second below, if I change the dimension of either JScrollPane it
changes the second one. So, the result is I either get a large left
JScrollPane or a small right JScrollPane.

I'd also like to remove any spacing between these 2 tables.

Third, I also tried to put each table into a separate JPanel and put
all this into a JScrollPane, but it (appeared to) yield the same
results as the second thing I tried.

What are the details to accomplish this.

Thanks,

class ParallelTables {
    static JScrollPane createTableA() {
        DefaultTableModel model = new DefaultTableModel(100, 1);
        for (int row=model.getRowCount(); --row>=0;) {
            model.setValueAt(row, row, 0);
        }
        JTable table = new JTable(model);
        return new JScrollPane(table);
    }

    static JScrollPane createTableB() {
        DefaultTableModel model = new DefaultTableModel(100, 5);
        for (int row=model.getRowCount(); --row>=0;) {
            model.setValueAt(row, row, 0);
        }
        JTable table = new JTable(model);
        return new JScrollPane(table);
    }

    public static void main(String[] args) throws Exception {

        JScrollPane scrollerA = createTableA();
        JScrollPane scrollerB = createTableB();
        scrollerA.setVerticalScrollBarPolicy(
                JScrollPane.VERTICAL_SCROLLBAR_NEVER);
        // the following statement binds the same BoundedRangeModel to
both vertical scrollbars.
        scrollerA.getVerticalScrollBar().setModel(
                scrollerB.getVerticalScrollBar().getModel());
        JPanel panel = new JPanel();
        panel.add(scrollerA);
        panel.add(scrollerB);
        JFrame frame = new JFrame();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.add(panel);
        frame.pack();
        frame.setVisible(true);
    }
