JTable Not Displaying from Window Builder Eclipse - eclipse

Question

I've just started to use the Eclipse Window Builder plugin to create a JFrame for my program but when adding a JTable it's just not showing up. The program acts like it's there but won't show it.
public class Stock extends JFrame {
private static final long serialVersionUID = -4904110593143929972L;
private JPanel contentPane;
private JTable table;
/**
* Launch the application.
*/
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
Stock frame = new Stock();
frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
/**
* Create the frame.
*/
public Stock() {
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setBounds(100, 100, 450, 300);
JMenuBar menuBar = new JMenuBar();
setJMenuBar(menuBar);
JMenu mnNewMenu = new JMenu("Add");
menuBar.add(mnNewMenu);
JMenu mnNewMenu_1 = new JMenu("Delete");
menuBar.add(mnNewMenu_1);
JMenu mnNewMenu_2 = new JMenu("Edit");
menuBar.add(mnNewMenu_2);
contentPane = new JPanel();
contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
setContentPane(contentPane);
contentPane.setLayout(null);
table = new JTable();
table.setBounds(10, 230, 414, -221);
contentPane.add(table);
loadTable();
}
public void loadTable() {
String[] columnNames = {"Key",
"Name",
"Quantity",
"Price per unit"};
Object[][] data = {
{"1","Name","10","�2.40"}};
table = new JTable(data, columnNames);
contentPane.add(table);
}
}
Like I said, I've only just started with Window Builder so it's probably just simple but I can't figure it out.

Sorry the issue was this line, "
contentPane.setLayout(null);" no idea how it got there. Ah well least its working :)
