Can I sort by clicking on column headings in Lion?

Question

I get search results, and I used to be able to click on the column headings and sort ascending/descending. Do I have to choose from the sort menu? And how do I reverse the sort?

import javax.swing.table.*;
public class Example {
    public static void main(String[] args) {
        final JTable table = new JTable(10,6);
        JTableHeader header = table.getTableHeader();
        header.addMouseListener(new MouseAdapter() {
            public void mouseClicked(MouseEvent evt) {
                Point pt = evt.getPoint();
                int colIdx = table.columnAtPoint(pt);
                int modIdx = table.convertColumnIndexToModel(colIdx);
                //for example:
                System.out.println(table.getModel().getColumnName(modIdx));
        JFrame f = new JFrame("Example");
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.getContentPane().add(new JScrollPane(table));
        f.pack();
        f.setLocationRelativeTo(null);
        f.setVisible(true);
