In this case IAccessible2::indexInParent + will return the child index which then can be used when calling IAccessibleTable::rowIndex + and IAccessibleTable::columnIndex. + + However, in some cases that kind of implementation will not be possible. When + the table cells are not direct children of a table, the object representing + the cell can define a "table-cell-index" object attribute identifying the 0 + based table cell index. This object attribute is obtained by parsing the + attribute string returned by IAccessible2::attributes. The "table-cell-index" + attribute can be used just like a child index of the typical case. ATs should + first test for the presence of the "table-cell-index" attribute and if it is not + present then IAccessible2::indexInParent can be used as in the typical case + where cells are direct children of the table. + + The range of valid coordinates for this interface are implementation dependent. + However, that range includes at least the intervals from the from the first row + or column with the index 0 up to the last (but not including) used row or column + as returned by IAccessibleTable::nRows and IAccessibleTable::nColumns. + + Note that newer implementations are now using IAccessibleTable2 and IAccessibleTableCell + rather than this interface. +*/ +[object, uuid(35AD8070-C20C-4fb4-B094-F4F7275DD469)] +interface IAccessibleTable : IUnknown +{ + + /** @brief Returns the accessible object at the specified row and column in + the table.
