## Interface AccessibleExtendedTable

- All Superinterfaces:
    AccessibleTable
  All Known Implementing Classes:
    JTable.AccessibleJTable

      public interface AccessibleExtendedTable
      extends AccessibleTable

  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.
  Since:
    1.4

    - #### getAccessibleRow

          int getAccessibleRow(int index)

      Returns the row number of an index in the table.

      Returns:
        the zero-based column of the table if one exists; otherwise -1.

    - #### getAccessibleIndex

          int getAccessibleIndex(int r,
                                 int c)

      Returns the index at a row and column in the table.
      Parameters:
        `r` - zero-based row of the table
        `c` - zero-based column of the table
