JTable selects more cells than clicked

Question

I am writing an application that uses a JTable and I would like to be able to select individual cells so I can interact with the selected cells. The problem is that when I select a certain number of cells, the JTable thinks I have clicked more than I actually have. For instance, I click 3 cells and the JTable automatically selects a 4th.

Here is an image of my issue. I select 3 cells in the order numbered in the image, and a 4th one is selected after selecting the 3rd.

How can I solve this issue?

Runnable example. My table application looks identical to this(obviously no menus or extra crap but this is how it is setup).

import java.awt.BorderLayout;
import java.awt.EventQueue;

import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.ListSelectionModel;
import javax.swing.UIManager;
import javax.swing.border.EmptyBorder;
import javax.swing.table.DefaultTableModel;

public class TestTable extends JFrame {

    private JPanel contentPane;
    private DefaultTableModel dbModel;
    private JTable table;
    private JScrollPane scrollPane;

    public static void main(String[] args) {
        EventQueue.invokeLater(new Runnable() {
            public void run() {
                try {
                    UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
                    TestTable frame = new TestTable();
                    frame.setLocationRelativeTo(null);
                    frame.setVisible(true);
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        });
    }

    public TestTable() {
        super("Test Table");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setBounds(100, 100, 800, 500);

        String[] columnNames = {"Name","Sport","Years Played"};
        Object[][] data = {{"Tim","Baseball","4"},
                {"Josh","Hockey","6"},
                {"Jessica","Volleyball","3"}};

        dbModel = new DefaultTableModel(data, columnNames);
        table = new JTable(dbModel);
        table.setSelectionMode(ListSelectionModel.MULTIPLE_INTERVAL_SELECTION);
        table.getColumnModel().setColumnSelectionAllowed(true);
        table.setCellSelectionEnabled(true);
        scrollPane = new JScrollPane(table);
        contentPane = new JPanel();
        contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
        contentPane.setLayout(new BorderLayout(0, 0));
        contentPane.add(scrollPane, BorderLayout.CENTER);
        setContentPane(contentPane);
    }
}

To enable single cell selection, use setCellSelectionEnabled(true), which "treats the intersection of the row and column selection models as the selected cells." See also this related answer.
