需要实现如下效果
一般ERP中,订单数据都分为汇总信息与明细信息,然后在查询的时候一次性从后台查询多条订单json数据,并将汇总信息展示到表格中。但是明细信息也是用户需要关注的,比如用户可能会想知道某个订单里面具体包含哪些商品,下单数量分别是多少。这时候就需要能够点击具体汇总信息行数据的时候,在下方展示出对应的明细数据。
实现要点
1、主表格绑定 @expand-change 事件
<el-table v-loading="loading" :data="data" size="small" border style="width: 100%;" @expand-change="rowExpand">
2、增加展开列,并在展开列中再加一个table(作为子表)
<el-table-column type="expand" prop="">
<template slot-scope="">
<el-table :data="orderDetailData">
<el-table-column label="订单编号" prop="orderId"/>
<el-table-column label="商品名称" prop="skuName"/>
<el-table-column label="购买数量" prop="purchaseNum"/>
<el-table-column label="价格" prop="skuPrice"/>
<el-table-column label="商品编码" prop="venderSku"/>
<el-table-column label="单品优惠" prop="discount"/>
</el-table>
</template>
</el-table-column>
3、methods中增加rowExpand方法具体实现
rowExpand(row, expandeRows) {
console.log('点开了' + row.orderId)
console.log(row.orderDetails)
const _this = this
_this.orderDetailData = row.orderDetails
}
完整代码如下
<template>
<div class="app-container">
<eHeader :query="query"/>
<!--表格渲染-->
<el-table v-loading="loading" :data="data" size="small" border style="width: 100%;" @expand-change="rowExpand">
<el-table-column type="expand" prop="">

<el-table-column label="商品名称" prop="skuName"/>
<el-table-column label="购买数量" prop="purchaseNum"/>
<el-table-column label="价格" prop="skuPrice"/>
<el-table-column label="商品编码" prop="venderSku"/>
<el-table-column label="单品优惠" prop="discount"/>
</el-table>
</template>
</el-table-column>
<el-table-column prop="orderId" label="订单编号" align="left" width="120"/>

<el-table-column label="操作" width="150px" align="center">
<template slot-scope="scope">
<!-- <el-button slot="reference" type="primary" size="mini" @click="showDetail">订单详情</el-button> -->
<edit v-if="checkPermission(['ADMIN'])" :data="scope.row" :sup_this="sup_this"/>
<el-popover

<!--分页组件-->

坑
其实不能算做坑,只是自己对于VUE不熟悉自己坑了自己
data() {
return {
// delLoading: false, sup_this: this, orderDetailData: [{ orderId: '11111', skuName: 'ddddddd' }, { orderId: '22222', skuName: 'ffffffff' }]
delLoading: false, sup_this: this, orderDetailData: null
}
},
data中需要给orderDetailData给个null值,那么后面的rowExpand方法中再给_this.orderDetailData 赋值界面上的数据才会重新渲染。这个问题在官方文档中有说明:
