/**
* 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, SWT.VIRTUAL | SWT.BORDER);
* table.setItemCount (1000000);
* table.addListener (SWT.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 normally make sense to add <code>Control</code> children to
* it, or set a layout on it, unless implementing something like a cell
* editor.
* </p><p>

* <dd>SINGLE, MULTI, CHECK, FULL_SELECTION, HIDE_SELECTION, VIRTUAL, NO_SCROLL</dd>
* <dt><b>Events:</b></dt>
* <dd>Selection, DefaultSelection, SetData, MeasureItem, EraseItem, PaintItem</dd>
* </dl>
