Skapa, manipulera eller ta bort scenarier från ark med JavaScript via C++

Contents
[ ]

Aspose.Cells erbjuder några användbara klasser, exempelvis ScenarioCollection, Scenario, ScenarioInputCellCollection och ScenarioInputCell. Den ger även egenskapen Worksheet.scenarios. Kodexemplet nedan öppnar en XLSX-fil som innehåller scenarier och tar bort ett befintligt scenario. Det lägger också till ett nytt scenario till arbetsbladet innan Excel-filen sparas. Exemplet använder en mycket enkel mallfil som innehåller ett scenario.
