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);
 
     void columnHeaders(AXObjectVector&);
     void rowHeaders(AXObjectVector&);
 
     // an object that contains, as children, all the objects that act as headers
     AXObject* headerContainer();
 
 protected:
     AXObjectVector m_rows;
     AXObjectVector m_columns;
 
     Member<AXObject> m_headerContainer;
     bool m_isAXTable;
 
     bool hasARIARole() const;
     virtual bool isTableExposableThroughAccessibility() const;
     bool computeAccessibilityIsIgnored(IgnoredReasons* = nullptr) const final;
 };
 
 DEFINE_AX_OBJECT_TYPE_CASTS(AXTable, isAXTable());
 
 } // namespace blink
 
 #endif // AXTable_h
