Disable JTable rowsorter for HeaderView

Question

I am having 2 JTables, one for displaying the rows and one for displaying the data:

Problem: When the data table are sorted, also the rows are sorted:

Is it possible to make the "RowHeaderView" table to not get sorted like the data table?

public class SimpleJTableHeader extends JFrame {

    public JTable table;

    public SimpleJTableHeader() {

        // CREATE A JTABLE
        Object rowData[][] = { { "a" }, { "b" }, { "c" }, { "d" } };
        Object columnNames[] = { "1" };
        table = new JTable(rowData, columnNames);
        table.setRowHeight(20);
        table.setAutoCreateRowSorter(true);

        JScrollPane scrollPane = new JScrollPane(table);

        // ADD ROW NUMBERS TO THE TABLE
        scrollPane.setRowHeaderView(getHeaderTable());

        // SHOW TABLE
        JFrame frame = new JFrame();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.add(scrollPane, BorderLayout.CENTER);
        frame.setSize(300, 150);
        frame.setVisible(true);
    }

    public JTable getHeaderTable() {
        final AbstractTableModel model = new AbstractTableModel() {

            private static final long serialVersionUID = 1L;

            @Override
            public int getColumnCount() {
                return 1;
            }

            @Override
            public Object getValueAt(int row, int column) {
                return table.convertRowIndexToModel(row);
            }

            @Override
            public int getRowCount() {
                return table.getRowCount();
            }
        };
        JTable headerTable = new JTable(model);
        headerTable.setPreferredScrollableViewportSize(new Dimension(40, 0));
        headerTable.setRowHeight(20);
        return headerTable;
    }

    public static void main(String args[]) {
        new SimpleJTableHeader();
    }
}

Thanks to mKorbel the new correct getHeaderTable method:

public JTable getHeaderTable() {
    DefaultTableModel model = new DefaultTableModel() {

        private static final long serialVersionUID = 1L;

        @Override
        public int getColumnCount() {
            return 1;
        }

        @Override
        public boolean isCellEditable(int row, int col) {
            return false;
        }

        @Override
        public int getRowCount() {
            return table.getRowCount();
        }

        @Override
        public Class<?> getColumnClass(int colNum) {
            switch (colNum) {
            case 0:
                return String.class;
            default:
                return super.getColumnClass(colNum);
            }
        }
    };

    JTable headerTable = new JTable(model);
    for (int i = 0; i < table.getRowCount(); i++) {
        headerTable.setValueAt((i + 1), i, 0);
    }
    headerTable.setPreferredScrollableViewportSize(new Dimension(40, 0));
    headerTable.setRowHeight(20);
    return headerTable;
}
