Mögliche Verwendungsszenarien
Wenn Sie eine Pivot-Tabelle mit bekannten Daten erstellen und filtern möchten, müssen Sie lernen und den Filter verwenden. Es kann Ihnen helfen, die gewünschten Daten effektiv herauszufiltern. Durch Verwendung der Aspose.Cells for JavaScript API via C++ können Sie Filter auf Feldwerte in Pivot-Tabellen hinzufügen.
Hinzufügen eines Filters in Pivot-Tabellen mit Aspose.Cells for JavaScript via C++
Bitte sehen Sie sich den folgenden Beispielcode an. Es legt die Daten fest und erstellt darauf basierend eine Pivot-Tabelle. Fügen Sie dann einen Filter im Zeilenfeld der Pivot-Tabelle hinzu. Schließlich speichert es die Arbeitsmappe im Format output XLSX. Nach Ausführung des Beispielcodes wird eine Pivot-Tabelle mit einem Top-10-Filter zum Arbeitsblatt hinzugefügt.
