Möjliga användningsscenario
En slicer används för att snabbt filtrera data. Den kan användas för att filtrera data både i en tabell eller pivottabell. Microsoft Excel gör det möjligt att skapa en slicer genom att välja en tabell eller pivottabell och sedan klicka på Infoga > Slicer. Aspose.Cells for JavaScript via C++ tillåter också att skapa slicer med hjälp av Worksheet.slicers.add()-metoden.
Skapa skärva till en pivot-tabell
Se följande exempel. Det laddar den exempel-Excel-filen som innehåller pivottabellen. Det skapar sedan slicern baserat på det första grundläggande pivottjänstfältet. Slutligen sparar det arbetsboken i utdata XLSX och utdata XLSB-format. Följande skärmavbild visar slicern som skapats av Aspose.Cells for JavaScript via C++ i Excel-filen.

Skapa skärva till Excel-tabell
Vänligen se det följande provkoden. Den laddar provmappen som innehåller en tabell. Sedan skapar den en slicer baserad på den första kolumnen. Slutligen sparar den arbetsboken i output XLSX format.
