Verbergen der Anzeige von Nullwerten im Arbeitsblatt mit JavaScript über C++

Contents
[ ]

Um Nullwerte in einem Arbeitsblatt in Microsoft Excel zu verstecken (z. B. Microsoft Excel 2003):

  1. Wählen Sie im Menü Extras die Option Optionen und dann den Tab Ansicht aus.
  2. Deaktivieren Sie die Option Nullwerte.
  3. Klicken Sie auf OK.

Siehe den folgenden Beispielcode, der das Verbergen von Nullen mit Aspose.Cells for JavaScript über C++ demonstriert.
