所以我一直试图在IE中使用javascript将HTML表格导出为excel。看起来更新的IE浏览器不允许这样（版本11）。 来自IE的不同反馈是：
1
The webpage cannot be displayed
Most likely cause:
•Some content or files on this webpage require a program that you don't have installed.
没有任何反应......
使用activeX时，它告诉我我没有这个支持的应用程序，建议我在应用程序商店中找到它...
以下是我尝试过的一些例子：
var tableToExcel = (function () {
var uri = 'data:application/vnd.ms-excel;base64,'
, template = '<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"><head><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet><x:Name>{worksheet}</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></head><body><table>{table}</table></body></html>'
, base64 = function (s) { return window.btoa(unescape(encodeURIComponent(s))) }
, format = function (s, c) { return s.replace(/{(\w+)}/g, function (m, p) { return c[p]; }) }
return function (table, name, filename) {
if (!table.nodeType) table = document.getElementById(table)
var ctx = { worksheet: name || 'Worksheet', table: table.innerHTML }
document.getElementById("dlink").href = uri + base64(format(template, ctx));
document.getElementById("dlink").download = filename;
document.getElementById("dlink").click();
}
})()
和
<script type="text/javascript">
var tableToExcel = (function() {
var uri = 'data:application/vnd.ms-csv;base64,'
, template = '<html xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas- microsoft-com:office:excel"'

, base64 = function(s) { return window.btoa(unescape(encodeURIComponent(s))) }
, format = function(s, c) { return s.replace(/{(\w+)}/g, function(m, p) { return c[p]; }) }
return function(table, name) {

var ctx = {worksheet: name || 'Worksheet', table: table.innerHTML}
window.location.href = uri + base64(format(template, ctx))

function fnExcelReport()

任何人都有适用于所有浏览器+ IE（版本7-11）的解决方案吗？
