AutoAnpassa Rader för Sammanfogade Celler med JavaScript via C++

]
Microsoft Excel har en funktion som låter dig automatiskt justera höjden på en cell enligt dess innehåll. Funktionen kallas automatisk anpassning av rader. Microsoft Excel tillämpar inte automatisk anpassning på sammanslagna celler som standard. Ibland blir funktionen viktig för en användare som verkligen behöver implementera automatisk anpassning av rader även på sammanslagna celler.
Hur man använder AutoFitMergedCellsType för att autofita rader
Aspose.Cells for JavaScript via C++ stöder denna funktion genom AutoFitterOptions.autoFitMergedCellsType-API:et. Med detta API är det möjligt att automatiskt anpassa rader i ett kalkylblad inklusive sammanslagna celler. Här är en lista över alla möjliga typer av auto-anpassning av 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.
