title: Align the label column of different DesignGridLayout
body: <p>Consider two <code>JPanel</code> instances using <a href="https://designgridlayout.java.net/" rel="nofollow noreferrer">DesignGridLayout</a>, like the following:</p>
  
  <pre><code>JFrame demoApplicationFrame = new JFrame();
  JPanel singleDesignGridLayout1 = new JPanel();
  DesignGridLayout layout1 = new DesignGridLayout(singleDesignGridLayout1);
  layout1.row().grid(new JLabel("Short lbl1")).add(new JTextField(""));
  layout1.row().grid(new JLabel("Short lbl2")).add(new JTextField(""));
  
  JPanel singleDesignGridLayout2 = new JPanel();
  DesignGridLayout layout2 = new DesignGridLayout(singleDesignGridLayout2);
  layout2.row().grid(new JLabel("A bit longer label"))
      .add(new JTextField(""));
  layout2.row().grid(new JLabel("Another long label here"))
      .add(new JTextField(""));
  
  demoApplicationFrame.getContentPane().add(singleDesignGridLayout1,
       BorderLayout.NORTH);
  demoApplicationFrame.getContentPane().add(singleDesignGridLayout2,
      BorderLayout.SOUTH);
  </code></pre>
  
  <p>Executing that code, will create this window:</p>

  <p>Is it possible to align the column for labels of the two panels?</p>
