How do I export html table data as .csv file?        https://stackoverflow.com/questions/7161113/how-do-i-export-html-table-data-as-csv-file二、原理：    data协议方式：对于支持data协议的浏览器，可以将html或是csv先用js base64处理，然后前缀data:application/vnd.ms-excel;base64,，即可使浏览器将其中的数据当做excel来处理，浏览器将提示下载或打开excel文件,可惜的是ie不支持。extjs的官网有一个grid的plugin，实现导出xhtml格式的伪excel文件，就是这么做的。三、Example
