导出execl表格的使用

在vue中使用excel

使用方法

1.安装依赖

npm install vue-json-excel


2.在项目的入口文件(main.js)中引入

import Vue from 'vue'
import JsonExcel from 'vue-json-excel'

Vue.component('downloadExcel', JsonExcel)

3.在模板中使用

<download-excel
:data = "json_data"
:fields = "json_fields"
name = "用户统计列表">
导出Excel
</download-excel>

4.Excel表格表头的设置

export default{
  data(){
    return{
     json_fields: { //导出Excel表格的表头设置
        '序号': 'type',
        '姓名': 'userName',
        '年龄': 'age',
        '手机号': 'phone',
        '注册时间': 'createTime',
      },
    }
  }
}

5.Excel表格中的数据

export default{
  data(){
    return{
      json_data:[
        {"userName":"张三","age":18,"gender":"phone":15612345612,"createTime":"2019-10-22"},
        {"userName":"李四","age":17,"gender":"phone":15612345613,"createTime":"2019-10-23"},
        {"userName":"王五","age":19,"gender":"phone":15612345615,"createTime":"2019-10-25"},
        {"userName":"赵六","age":18,"gender":"phone":15612345618,"createTime":"2019-10-15"},
      ]
    }
  }
}

 js使用方法

安装依赖

npm i xlsx

引入依赖

import XLSX from 'xlsx'

 代码使用

 // 初始化存放合并表头的list
        let arr = []
        // 存放二级表头的集合,因为使用es6语法中的在Mis平台不支持
        let head = []
        // 将二级表头的数据进行整理整理成字符串数组
        this.userInsuranceTableHeader.map(el => {
          arr.push(el.columnName)
        })
       //  把数据转换成字符串
        let table = this.tableDate.map(res => Object.values(res))
        // 特殊处理,需要拆分的地方进行整理
        table.map(arr => {
          let aaa = arr[12].split("、")
          aaa.indexOf("养老保险") > 0 ? arr.splice(4,0,"√") :arr.splice(4,0,null)
          aaa.indexOf("失业保险") > 0 ? arr.splice(5,0,"√") :arr.splice(5,0,null)
          aaa.indexOf("工伤保险") > 0? arr.splice(6,0,"√"):arr.splice(6,0,null)
          aaa.indexOf("医疗保险") > 0? arr.splice(7,0,"√"):arr.splice(7,0,null)
          aaa.indexOf("住房公积金") > 0? arr.splice(8,0,"√"):arr.splice(8,0,null)
          arr.splice(17, 1);
        })
         // 需要打印的格式,需要合并的把合并内容添加null   
        let aoa = [
          ["增加增加((	需要提供身份证复印件需要提供身份证复印件	,合同复印件合同复印件	))",null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,,null,null],
          ["序号","姓名","身份证号码","民族","险种	(打√	)",null,null,null,null,"参保起始时间","岗位工种","合同起始时间","合同终止时间","社保基数","医保基数","公积金基数","联系电话","家庭地址"],
          [null,null,null,null,"养老","失业","工商","医疗","公积金","(可从当年一月份补收)",null,null,null,null,null,null,,null,null],
          // arr,
          ...table
        ]
        // 转换成xlsx的格式
        const sheet1 = XLSX.utils.aoa_to_sheet(aoa);
        
        sheet1['!merges'] = [
