注意，https://cdn.jsdelivr.net/npm/luckysheet/dist/luckysheet.umd.js这个路径意思是会拉取到最新的luckysheet代码，但是如果Luckysheet刚刚发布，jsdelivr网站可能还没来得及从npm上同步过去，故而使用这个路径还是会拉到上一个版本，我们推荐您直接指定最新版本。
想要指定Luckysheet版本，请在所有的CDN依赖文件后面加上版本号，如：https://cdn.jsdelivr.net/npm/luckysheet@2.1.12/dist/luckysheet.umd.js。

template页面使用基础的配置

<template>

        <div class="head_wrap">
