Mögliche Verwendungsszenarien
Ein Slicer wird verwendet, um Daten schnell zu filtern. Es kann sowohl in einer Tabelle als auch in einer Pivot-Tabelle verwendet werden. Microsoft Excel ermöglicht das Erstellen eines Slicers, indem Sie eine Tabelle oder Pivot-Tabelle auswählen und dann auf Einfügen > Slicer klicken. Aspose.Cells for JavaScript via C++ ermöglicht auch die Erstellung eines Slicers mit der Methode Worksheet.slicers.add().
Erstellen Sie ein Schneidwerkzeug zu einem Pivot-Table
Siehe folgenden Beispielcode. Es lädt die Beispieldatei Excel, die die Pivot-Tabelle enthält. Dann erstellt es den Slicer basierend auf dem ersten Basis-Pivotfeld. Schließlich speichert es die Arbeitsmappe im Ausgabe XLSX und Ausgabe XLSB Format. Der folgende Screenshot zeigt den durch Aspose.Cells for JavaScript via C++ erstellten Slicer in der Ausgabedatei Excel.

Erstellen Sie ein Schneidwerkzeug zu Excel-Tabelle
Bitte beachten Sie den folgenden Beispielcode. Es lädt die Beispieldatei Excel, die eine Tabelle enthält. Anschließend wird der Slicer basierend auf der ersten Spalte erstellt. Schließlich speichert es die Arbeitsmappe im Format output XLSX.
