推荐答案

$("#btnExport").click(function(e) {
  let file = new Blob([$('#dvData').html()], {type:"application/vnd.ms-excel"});

let url = URL.createObjectURL(file);

let a = $("<a />", {
  href: url,
  download: "filename.xls"
})
.appendTo("body")
.get(0)
.click();
  e.preventDefault();
});

body {
    font-size: 12pt;
    font-family: Calibri;
    padding : 10px;
}
table {
    border: 1px solid black;
}
th {
    border: 1px solid black;
    padding: 5px;
    background-color:grey;
    color: white;
}
td {
    border: 1px solid black;
    padding: 5px;
}
input {
    font-size: 12pt;
    font-family: Calibri;
}
