Möjliga användningsscenarier
Du kan ange formelfält när du importerar data till ditt kalkylblad med hjälp avImportTableOptions.setFormulas() metod. Denna metod tar den booleska arrayen där värdetSannbetyder att fältet är ett formelfält. Till exempel, om det tredje fältet är ett formelfält, kommer det tredje värdet i matrisen att varaSann.
