  * table format.
  * Applications can determine if an object supports the
  * AccessibleExtendedTable interface by first obtaining its
  * AccessibleContext and then calling the
  * {@link AccessibleContext#getAccessibleTable} method.
  * If the return value is not null and the type of the return value is
  * AccessibleExtendedTable, the object supports this interface.
