vue.js中使用Export2Excel导出Excel表格

1.安装依赖
npm install -S file-saver xlsx
npm install -D script-loader

2.导入两个JS
下载Blob.js和Export2Excel.js，在src目录下新建Excel文件夹，里面放入Blob.js和Export2Excel.js两个JS文件

3.main.js 引入文件
import Blob from './excel/Blob'
import Export2Excel from './excel/Export2Excel.js'

4.组件中使用
// 导出的方法
    loadingFun () {
      loadingInstance = Loading.service(options)
      this.dowExcelList = []
      this.getExportExcelData()
    },
    async getExportExcelData () {
      this.dowCurrentPage++
      const params = `?tenantId=${this.search.tenantId}&projectId=${this.search.projectId}&createTimeStart=${this.search.createTimeStart}
                      &createTimeEnd=${this.search.createTimeEnd}&identity=${this.search.identity}&sort=${this.search.sort}
                      &pageSize=10¤tPage=${this.dowCurrentPage}`
      const result = await getDownStatisticsGetAgentRankList(params)
      this.dowExcelList = this.dowExcelList.concat(result.data)
      if (this.dowCurrentPage < result.page.pageCount) {
        let totalPage = result.page.pageCount
        let currentPage = result.page.currentPage
        let Speed = parseInt((currentPage / totalPage) * 100)
        loadingInstance.text = `导出进度 ${Speed}%`
        this.getExportExcelData(params)
      } else {
        this.export2Excel()
      }
    },
    export2Excel () {
      loadingInstance.text = `导出进度完成开始下载`
      require.ensure([], () => {
        const { exportJsonToExcel } = require('../../vendor/Export2Excel')
        const tHeader = ['渠道身份', '姓名', '全部报备'] // 上面设置Excel的表格第一行的标题
        const filterVal = ['identityname', 'name', 'allNum'] // 上面的index、nickName、name是tableData里对象的属性
        const list = this.dowExcelList // 把data里的tableData存到list
        const data = this.formatJson(filterVal, list)
        exportJsonToExcel(tHeader, data, '列表excel')
      })
      setTimeout(() => {
        loadingInstance.close()
      }, 500)
    },
    formatJson (filterVal, jsonData) {
      return jsonData.map(v => filterVal.map(j => v[j]))
    }
