Standard Schriftart beim Rendern von Tabellen in HTML mit JavaScript über C++ festlegen

Festlegen der Standardschriftart beim Rendern von Tabellenkalkulationen in HTML

Der folgende Beispielscode erstellt eine Arbeitsmappe und fügt einen Text in Zelle B4 des ersten Arbeitsblatts hinzu und legt die Schriftart auf eine unbekannte/nicht vorhandene Schriftart fest. Dann speichert er die Arbeitsmappe in HTML, indem er verschiedene Standardschriftart-Namen wie Courier New, Arial, Times New Roman usw. festlegt.

Das Screenshot zeigt die Auswirkung der Einstellung verschiedener Standard-Schriftartnamen über die Eigenschaft HtmlSaveOptions.defaultFontName.

Der Code generiert die Ausgabe-HTML-Datei mit Courier New, die Ausgabe-HTML mit Arial und die Ausgabe-HTML-Datei mit Times New Roman.
