title: JTable not showing after adding to JScrollPane?
body: <p>I have a JTable which shows up fine. If I place the Table in a JScrollPane it does not show anymore. Why not? I would like to add both tables each in an own JScrollPane. Here my code in which I am only trying to add a JScrollPane to the first table:</p>
  
  <pre><code>private void initialize() {
      frame = new JFrame();
      frame.setBounds(100, 100, 1000, 800);
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      frame.getContentPane().setLayout(null);
  
      JProgressBar progressBar = new JProgressBar();
      progressBar.setBounds(50, 68, 700, 14);
      frame.getContentPane().add(progressBar);
  
      JTextPane txtpnAutomotiveHmi = new JTextPane();
      txtpnAutomotiveHmi.setText("Automotive HMI");
      txtpnAutomotiveHmi.setBounds(362, 21, 205, 20);
      frame.getContentPane().add(txtpnAutomotiveHmi);
  
  
      testcase_table = new JTable();
      testcase_table.setBounds(50, 125, 350, 426);
      JScrollPane scroll_testcase = new JScrollPane(testcase_table);
      frame.getContentPane().add(scroll_testcase);
  
      teststep_table = new JTable();
      teststep_table.setBounds(399, 125, 350, 426);
      frame.getContentPane().add(teststep_table);
  }
  </code></pre>
  
  <p>Thanks.</p>
