Berechnung der Array Formel von Datentabellen mit JavaScript via C++

Contents
[ ]

Im folgenden Beispiellcode haben wir die Quellexceldatei verwendet. Wenn Sie den Wert von Zelle B1 auf 100 ändern, werden die Werte der Datentabelle, die mit Gelb gefüllt sind, wie in den folgenden Bildern gezeigt, zu 120. Der Beispiellcode generiert die Ausgabepdf.
