How about if we just combine this into columnCount() and rowCount(), with a
comment saying that they might not match the number of columns and rows.

For example:

    // The column count and row count are virtual and can be
    // overridden by ARIA, so columnCount() may not be the
    // same as columns().size(), for example.
    int columnCount();
    int rowCount();

+    int ariaRowCount();
+
     unsigned columnCount();
     unsigned rowCount();
     AXTableCell* cellForColumnAndRow(unsigned column, unsigned row);
