Formatera slicer med JavaScript via C++

Möjliga användningsscenario

Du kan formatera slicern i Microsoft Excel genom att ange antalet kolumner eller genom att ställa in dess stil, etc. Aspose.Cells for JavaScript via C++ tillåter dig också att göra detta med hjälp av Slicer.numberOfColumns och Slicer.styleType-egenskaperna.
