+* Instances of this class implement a selectable user interface
+* object that displays a list of images and strings and issues
+* notification when selected.
+* <p>
+* The item children that may be added to instances of this class
+* must be of type <code>TableItem</code>.
+* </p><p>
+* Style <code>VIRTUAL</code> is used to create a <code>Table</code> whose
+* <code>TableItem</code>s are to be populated by the client on an on-demand basis
+* instead of up-front.  This can provide significant performance improvements for
+* tables that are very large or for which <code>TableItem</code> population is
+* expensive (for example, retrieving values from an external source).
+* </p><p>
+* Here is an example of using a <code>Table</code> with style <code>VIRTUAL</code>:
+* <code><pre>
+*  final Table table = new Table (parent, DWT.VIRTUAL | DWT.BORDER);
+*  table.setItemCount (1000000);
+*  table.addListener (DWT.SetData, new Listener () {
+*      public void handleEvent (Event event) {
+*          TableItem item = (TableItem) event.item;
+*          int index = table.indexOf (item);
+*          item.setText ("Item " + index);
+*          System.out.println (item.getText ());
+*      }
+*  });
+* </pre></code>
+* </p><p>
+* Note that although this class is a subclass of <code>Composite</code>,
+* it does not make sense to add <code>Control</code> children to it,
+* or set a layout on it.
