1.下载xlsx-style
npm install xlsx-style
xlsx-style核心模块 在 你安装路径\node_modules\xlsx-style\dist
2.示例代码
复制出 文件xlsx.full.min.js
编写示例代码:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>示例</title>
</head>
<body>
<script src="./xlsx.full.min.js"></script>
<script>
function saveAs(obj, fileName) {
var tmpa = document.createElement("a");
tmpa.download = fileName || "下载";
tmpa.href = URL.createObjectURL(obj);
tmpa.click();
setTimeout(function () {
URL.revokeObjectURL(obj);
}, 100);
}

var tmpWB = {
