  41
  42         The control itself does not do any assumptions about the concrete data
  43         it displays, this is encapsulated in an instance supporting the
  44         ->ITableModel interface.
  45
  46         Also, the control does not do any assumptions about how the model's
  47         content is rendered. This is the responsibility of a component
  48         supporting the ->ITableRenderer interface (the renderer is obtained from
  49         the model).
  50
  51         The control supports the concept of a <em>current</em> (or <em>active</em>
  52         cell).
  53         The control supports accessibility, this is encapsulated in IAccessibleTable
