Class AccessibleExtendedTable provides extended information about a user-interface component that presents data in a two-dimensional table format. Applications can determine if an object supports the AccessibleExtendedTable interface by first obtaining its AccessibleContext and then calling the AccessibleContext.getAccessibleTable method. If the return value is not null and the type of the return value is AccessibleExtendedTable, the object supports this interface.
