Möjliga användningsscenario
När du sätter ett värde i cellen som har ledande apostrof eller citattecken, döljer sedan Microsoft Excel det, men när du väljer cellen visas den ledande apostrof eller citattecken i en formlerad som visas i följande skärmbild.
Aspose.Cells for JavaScript via C++ döljer även det ledande apostrofen eller enkla citattecknet likt Microsoft Excel men ställer in Style.quotePrefix som true för den cellen. Om du tilldelar ett tomt stilark till cellen blir Style.quotePrefix återigen false. För att hantera detta tillhandahåller Aspose.Cells for JavaScript via C++ egenskapen Style.quotePrefix. När den är satt till false, uppdateras inte Style.quotePrefix alls och dess gamla värde behålls. Det betyder att om det gamla värdet av Style.quotePrefix var true, förblir det true och om det var false, förblir det false.
Bevara enskild citattecken prefiks av cellvärde eller område

Quote Prefix of Cell A1: False
Quote Prefix of Cell A1: True
When StyleFlag.quotePrefix is False, it means, do not update the value of Cell.Style.quotePrefix.
Similarly, when StyleFlag.quotePrefix is True, it means, update the value of Cell.Style.quotePrefix.
Quote Prefix of Cell A1: True
Quote Prefix of Cell A1: False
