Kopiera områden av Excel med JavaScript via C++

Introduktion

I Excel kan du markera ett område, kopiera området och sedan klistra in det med specifika alternativ på samma arbetsblad, andra arbetsblad eller andra filer.

Kopiera områden med Aspose.Cells for JavaScript via C++

Aspose.Cells for JavaScript via C++ erbjuder några överlagrade Range.copy(Range, PasteOptions) metoder för att kopiera området. Och Range.copyStyle(Range) kopierar endast stilen för området; Range.copyData(Range) kopierar endast värdet i området.

Kopiera område

Skapa två områden: källområdet och målordet, och kopiera sedan källområdet till målordet med metoden Range.copy.
