| 28 | * Class AccessibleExtendedTable provides extended information about | ||
| 29 | * a user-interface component that presents data in a two-dimensional | ||
| 30 | * table format. | ||
| 31 | * Applications can determine if an object supports the | ||
| 32 | * AccessibleExtendedTable interface by first obtaining its | ||
| 33 | * AccessibleContext and then calling the | ||
| 34 | * {@link AccessibleContext#getAccessibleTable} method. | ||
| 35 | * If the return value is not null and the type of the return value is | ||
| 36 | * AccessibleExtendedTable, the object supports this interface. | ||
