SpreadJSは、Microsoft Excelスタイルのテーマをサポートしており、各テーマは以下のようなCSSファイルで提供されています。
Excel 2007: gc.spread.sheets.xx.x.x.css
Excel 2013 Dark Gray: gc.spread.sheets.excel2013darkGray.xx.x.x.css
Excel 2013 Light Gray: gc.spread.sheets.excel2013lightGray.xx.x.x.css
Excel 2013 White: gc.spread.sheets.excel2013white.xx.x.x.css
Excel 2016 Colorful: gc.spread.sheets.excel2016colorful.xx.x.x.css
Excel 2016 Dark Gray: gc.spread.sheets.excel2016darkGray.xx.x.x.css
Excel 2016 Black: gc.spread.sheets.excel2016black.xx.x.x.css
ウェブページのヘッダセクションにスタイル参照を追加することで、テーマの利用が可能です。次に、例を示します。
参照するCSSファイルを変更することで、動的にテーマを変更することも可能です。この際、変更の適用にはrefreshメソッドの呼び出しが必要です。
