SpreadJS provides built-in themes. You can use the currentTheme method to get and set the current theme for the sheet, for example:
You can use the theme colors or standard colors to set cells' foreColor or backColor methods, as shown in this example.
You can specify the theme font directly through the GC.Spread.Sheets.Theme, or use the GC.Spread.Sheets.ThemeFont to define precisely:
When it's in the East Asian culture, you could specify the fontScriptCode on the cultureInfo firstly, the current theme font will used the East Asian font rather than the Latin font:
