            “<html><head><meta charset=’utf-8′ /></head><body>” +
            document.getElementsByTagName(‘table’)[0].outerHTML +
            ‘</body></html>’
        // 实例化一个Blob对象，其构造函数的第一个参数是包含文件内容的数组，第二个参数是包含文件类型属性的对象

        var a = document.getElementsByTagName(‘a’)[0]
        // 利用URL.createObjectURL()方法为a元素生成blob URL
        a.href = URL.createObjectURL(blob)
        // 设置文件名，目前只有Chrome和FireFox支持此属性
