在vue组件中，需要先安装xlsx和file-saver，使用命令如下：

npm install xlsx --save
npm install file-saver --save

在.vue 模板中代码如下

<template>
 <div id="app" >
        <button @click="downloadExl">导出</button>
        <div id="tableId">
            <table class="table table-bordered" style="min-width: 100%;">
                <thead>
                    <tr>
                        <th>#</th>
                        <th v-for="(item,index) in Object.keys(jsonData[0])" :key="index">
                            {{item}}
                        </th>
                    </tr>
                </thead>
                <tbody>
                    <tr v-for="(row,index) in jsonData" :key="index">
                        <th scope="row">{{index}}</th>
                        <td v-for="col in Object.keys(jsonData[0])">{{(row)[col]}}</td>
                    </tr>
                </tbody>
            </table>
        </div>
    </div>
</template>
<script>
var XLSX = require('xlsx')
var FileSaver = require('file-saver')
export default {
        data() {
            return {
                jsonData: [{
                    "姓名": "小杨",
                    "联系电话": "021-33829544",
                    "家庭地址": "浦东新区金桥镇五莲路1706号"
                }]
            }
        },
        methods: {
            downloadExl() {
                let wb = XLSX.utils.table_to_book(document.getElementById('tableId')),
                    wopts = {
                        bookType: 'xlsx',
                        bookSST: false,
                        type: 'binary'
                    },
                    wbout = XLSX.write(wb, wopts);

               FileSaver.saveAs(new Blob([this.s2ab(wbout)], {
                    type: "application/octet-stream;charset=utf-8"
                }), "个人简介表.xlsx");
            },
            s2ab(s) {
                if (typeof ArrayBuffer !== 'undefind') {
                    var buf = new ArrayBuffer(s.length);
                    var view = new Uint8Array(buf);
                    for (var i = 0; i != s.length; ++i) view[i] = s.charCodeAt(i) & 0xFF;
                    return buf;
                } else {
                    var buf = new Array(s.length);
                    for (var i = 0; i != s.length; ++i) buf[i] = s.charCodeAt(i) & 0xFF;
                    return buf;
                }
            }
        }
}
</script>

可以将vue表格中的数据，以excel文件导出。
