Skapa unionsområde med JavaScript via C++

Skapa unionsspann

Aspose.Cells ger möjlighet att skapa ett unionsområde genom att använda metoden WorksheetCollection.createUnionRange. Metoden tar emot två parametrar, adressen för att skapa unionsområdet och indexet för kalkylbladet. Metoden returnerar ett UnionRange objekt.

Följande kodexempel visar hur man skapar ett unionsområde med hjälp av metoden WorksheetCollection.createUnionRange. Den genererade filen är bifogad för referens.
