解决vue项目导出当前页Table为Excel

解决vue项目中导出当前页表格为Excel表格的方案

用到的技术：

• Vue2
• Element-ui
• file-saver
• xlsx

1、创建vue项目，安装element-ui

2、创建一个组件，组件内放入表格，和导出按钮

<template>
  <div>
    <!-- 导出的按钮 -->
    <el-button size="small" type="primary" icon="el-icon-download" @click="exportData"
      >导出</el-button
    >
    <!-- 表格数据 -->
    <el-table id="myTable" :data="tableData" style="width: 100%" border>
      <el-table-column prop="date" label="日期" width="180"> </el-table-column>
      <el-table-column prop="name" label="姓名" width="180"> </el-table-column>
      <el-table-column prop="address" label="地址"> </el-table-column>
    </el-table>
  </div>
</template>

<script>
export default {
  props: {},
  data() {
    return {
      tableData: [
        {
          date: '2016-05-02',
          name: '王小虎',
          address: '上海市普陀区金沙江路 1518 弄'
        },
        {
          date: '2016-05-04',
          name: '王小虎',
          address: '上海市普陀区金沙江路 1517 弄'
        },
        {
          date: '2016-05-01',
          name: '王小虎',
          address: '上海市普陀区金沙江路 1519 弄'
        },
        {
          date: '2016-05-03',
          name: '王小虎',
          address: '上海市普陀区金沙江路 1516 弄'
        }
      ]
    }
  },
  methods: {}
    
</script>

<style scoped lang="less"></style>

3、安装导出表格需要的插件【xlsx 和 file-saver】

npm install --save xlsx file-saver

4、在main.js中引入安装的依赖

// 引入导出excel的插件
import FileSaver from 'file-saver'
import * as XLSX from 'xlsx'
Vue.prototype.$FileSaver = FileSaver; //设置全局
Vue.prototype.$XLSX = XLSX; //设置全局

5、编写导出功能

 //导出功能
    exportData() {
      let excelName = '导出表格名称.xlsx'
      var xlsxParam = { raw: true } //转换成excel时，使用原始的格式
      // 克隆节点
      let tables = document.getElementById('myTable').cloneNode(true)
      // 判断是否为固定列，解决（为固定列时，会重复生成表格）
      if (tables.querySelector('.el-table__fixed') !== null) {
        tables.removeChild(tables.querySelector('.el-table__fixed'))
      }
      let table_book = this.$XLSX.utils.table_to_book(tables, xlsxParam)
      var table_write = this.$XLSX.write(table_book, {
        bookType: 'xlsx',
        bookSST: true,
        type: 'array'
      })
      try {
        this.$FileSaver.saveAs(
          new Blob([table_write], { type: 'application/octet-stream' }),
          excelName
        )
      } catch (e) {
        if (typeof console !== 'undefined') console.log(e, table_write)
      }
      return table_write
    }

搞定！！！
