AutoFit Rader för sammanslagna celler med Node.js via C++
Hur man använder AutoFitMergedCellsType för att autofita rader
Aspose.Cells for Node.js via C++ stöder denna funktion via API:et AutoFitterOptions.autoFitMergedCellsType. Med detta API är det möjligt att auto-anpassa rader i ett kalkylblad inklusive sammanslagna celler. Här är en lista över alla möjliga typer av auto-anpassning för sammanslagna celler:
- Ingen
- Första raden
- Sista raden
- Varje rad
Autofit rader för sammanslagna celler
Se följande kod, den skapar ett arbetsbok-objekt och lägger till flera arbetsblad. Använd olika metoder för autofit-operationer i varje blad. Skärmbilden visar resultaten efter körning av exempel-koden.
