title: How to show message in grid with table?
body: <p>I created a grid with TableViewer.</p>
  
  <p>In some cases, I want to hide the TableViewer and to a show message.</p>
  
  <p>This is how I created the TableViewer :</p>
  
  <pre><code>gridLayout = new GridLayout();
  Table table = new TableViewer(parent, SWT.MULTI | SWT.H_SCROLL | SWT.V_SCROLL |      SWT.FULL_SELECTION | SWT.BORDER )
  table.setLayoutData(gridLayout)
  </code></pre>
  
  <p>I know how to hide the table -  table.setVisible(false). The issue is where to set the message? I didn't create a textBox (SWT) for this.</p>
  
  <p>Do I need to create textBox (SWT) and to set the visible for false ( as default ) and only when I want to show message to show it as visible = true ?</p>
