最近在做一个信息采集管理系统,需要把采集到的信息导出到excle,先说说在vue中安装和引入table2excel
//安装
npm install js-table2excel
//引入
import table2excel from 'js-table2excel'
采集系统需要收集的信息包含姓名、手机号、身份证号、还有一项是上传图片;
模拟数据如下:
const data=[
{
name:"张三",
phone:"13512345678",
idCard:"412356198601251234",
image:"https://profile.csdnimg.cn/9/8/3/2_xiaoxiaojie12321"
},
{
name:"李四",
phone:"13612345678",
idCard:"412356198601251234",
image:"https://profile.csdnimg.cn/9/8/3/2_xiaoxiaojie12321"
},
{
name:"王五",
phone:"13712345678",
idCard:"412356198601251234",
image:"https://profile.csdnimg.cn/9/8/3/2_xiaoxiaojie12321"
}
]
需求是导出时将图片一块导出
下面是导出按钮上绑定的方法
exportExcel() {
const column=[
{
title: '姓名',
key: 'name',
type: 'text'
},
{
title: '手机号',
key: 'phone',
type: 'text'
},
{
title: '身份证号',
key: 'idCard',
type: 'text'
},
{
title: '图片',
key: 'image',
type: 'image',
width: 80,
height: 50
},
]
/** column数据的说明 */
// 1.title为列名
// 2.key为data数据每个对象对应的key
// 3.若为图片格式, 需要加type为image的说明,并且可以设置图片的宽高
const data = this.tableData
const excelName = `人员信息统计表`
table2excel(column, data, excelName)
}
本人亲测,这样确实可以导出数据中的图片,但是又出现了一个新问题,导出表格内的身份证号码显示成了科学计数法,这肯定不符合要求,找了半天的资料,也没找到一个合适的案例,后面收到网友提供的方法启发,才解决;
网友提供的方法如下:
只需在td上加上如下style,
<td style="mso-number-format:'\@';" ng-bind="data.paySerialNo"></td>
可是我想了半天,我是通过JSON数据导出的,我改吧这个代码加到哪儿;无奈之下准备去看看依赖代码:
源码文件路径 :node_modules\js-table2excel\index.js
下面是我修改后的代码
/* eslint-disable */
