Zeilen für zusammengeführte Zellen mit JavaScript via C++ automatisch anpassen

Microsoft Excel bietet eine Funktion, die es Ihnen ermöglicht, die Höhe einer Zelle automatisch an den Inhalt anzupassen. Die Funktion wird als automatische Anpassung von Zeilen bezeichnet. Microsoft Excel führt die Autofit-Operation nicht nativ bei zusammengeführten Zellen durch. Manchmal wird die Funktion für einen Benutzer, der wirklich eine automatische Anpassung von Zeilen in zusammengeführten Zellen benötigt, unerlässlich.
Wie man AutoFitMergedCellsType zum Anpassen von Zeilen verwendet
Aspose.Cells for JavaScript via C++ unterstützt diese Funktion durch die AutoFitterOptions.autoFitMergedCellsType API. Mit dieser API ist es möglich, Zeilen in einem Arbeitsblatt einschließlich zusammengeführter Zellen automatisch anzupassen. Hier ist eine Liste aller möglichen Typen des Auto-Fit-Layouts für zusammengeführte Zellen:
- Keine
- ErsteZeile
- LetzteZeile
- JedeZeile
AutoFit für zusammengeführte Zellen
Bitte siehe den folgenden Code, er erstellt ein Arbeitsbuch-Objekt und fügt mehrere Arbeitsblätter hinzu. Verwenden Sie verschiedene Methoden für AutoFit-Operationen in jedem Arbeitsblatt. Der Screenshot zeigt die Ergebnisse nach der Ausführung des Beispielcodes.
