网上查了挺多资料，都不兼容IE，要么就是不是通过json来导出excel表格；
直接上代码吧。
var tats= [{},{},{}] //这样的格式导出。
tats.forEach(function (item, index) {
var vote = {};
vote.id = index + 1;
vote.area = item.area
vote.depart = item.depart
vote.companyName = item.companyName
vote.personName = item.personName
vote.phone = item.phone
vote.cardId = item.cardId
vote.status = item.status
if (vote.status == 1) {
vote.status = "已接种";
} else if (vote.status == 0) {
vote.status = "未接种";
}
vote.cardId = vote.cardId + ' ' + " "
arr.push(vote)
})
var str = ['序号', '单位级别', '所属主管部门', '单位名称', '受种者姓名', '受种者电话', '身份证号码', '是否接种'];
Json2Excel(arr, exName, str)
