SpreadJS 全面支持Excel的各种主题。提供如下不同主题css文件以供选择：
Excel 2007: gc.spread.sheets.x.x.x.css
Excel 2013 White: gc.spread.sheets.excel2013white.x.x.x.css
Excel 2013 Light Gray: gc.spread.sheets.excel2013lightgray.x.x.x.css
Excel 2013 Dark Gray: gc.spread.sheets.excel2013darkgray.x.x.x.css
Excel 2016 Colorful: gc.spread.sheets.excel2016colorful.x.x.x.css
Excel 2016 Dark Gray: gc.spread.sheets.excel2016darkgray.x.x.x.css
可以通过添加它们中的任意一个css文件引用到页面头部来加载主题。例如：
你可以通过改变 css 文件引用来动态切换主题。你需要调用 Spread的 refresh 方法来应用改变。
