最近做的一个项目涉及到把数据导出到excel里面，网上找来找去，最终找到两种办法，废话不多说了
第一种:
拿到表格的id就可以抓取表格的数据，导出到excel，这种方式简单粗暴，引入这两个插件即可。
但是用这种方式会出现一种问题，就是当你的table有分页的情况下，这玩意只能抓取页面上的值，所以也不用多说了，其他分页的是导不出来的，值能导出当前分页的数据。
但是项目要求必须导出所有数据，这就出现了第二种解决方案，
使用起来也比较简单，拿到数据直接往里面塞就是了，最后调用方法。这样的话最终所有数据都出来了。
function JSONToExcelConvertor(JSONData, FileName, ShowLabel) {
var arrData = typeof JSONData != 'object' ? JSON.parse(JSONData) : JSONData;
var excel = '<table>';
//设置表头
var row = "<tr>";
for (var i = 0, l = ShowLabel.length; i < l; i++) {
row += "<td>" + ShowLabel[i].value + '</td>';
}
//换行
excel += row + "</tr>";
//设置数据
for (var i = 0; i < arrData.length; i++) {
var row = "<tr>";
for(var j=0;j<arrData[i].length;j++){
var value = arrData[i][j].value === "." ? "" : arrData[i][j].value;
row += '<td>' + value + '</td>';
}
excel += row + "</tr>";
}
excel += "</table>";
var excelFile = "<html xmlns:o='urn:schemas-microsoft-com:office:office' xmlns:x='urn:schemas-microsoft-com:office:excel' xmlns='http://www.w3.org/TR/REC-html40'>";
excelFile += '<meta http-equiv="content-type" content="application/vnd.ms-excel; charset=UTF-8">';
