说明： el-table有一个表格一级数据和二级数据显示的是一样的，像这种就可以用递归实现。
数据结构是这样子的：
tableData:[{
name: "Lucy",
age: 18,
mobile: "11111111111",
type: 1,
friends:[{
name: "Lucy-friend1"，
age: 16,
mobile: "11111111111"
},{
name: "Lucy-friend2"，
age: 16,
mobile: "11111111111"
}]
}]
像以上这种数据结构想要如下图一样显示：
我用的是el-table组件，所以单独建了一个组件用于表格递归显示。regionTableTemplate里expend中用到的递归显示二级数据
代码如下：
<template>
<el-table :data="tableData" class="table-sub" ref="regionTable" :show-header="showHeader" :row-class-name="isShowExpend">
<el-table-column type="expand">
<template slot-scope="scope">
<template v-if="scope.row.friends">
<regionTableTemplate class="in-table" :tableData="scope.row.friends" :showHeader="false"></regionTableTemplate>
</template>
</template>
</el-table-column>
<el-table-column prop="name" label="姓名"></el-table-column>
<el-table-column prop="age" label="年龄"></el-table-column>
<el-table-column prop="mobile" label="手机号"></el-table-column>
<el-table-column label="操作" width="220">
<template slot-scope="scope">
<el-button type="text">详情</el-button>
<el-button type="text"> 创建可用区</el-button>
<el-button :disabled="scope.row.type === 1?true:false" type="text">删除</el-button>
</template>
</el-table-column>
</el-table>
</template>
<script>
export default {
name: "regionTableTemplate",
props:{
tableData: Array,
showHeader: Boolean
},
methods:{
//展开行 用于没有friends数组即没有子数据
isShowExpend(row, index) {
if (row.row.friends&&row.row.friends) {
return ''
} else {
return 'hide-expand'
}
}
}
}
</script>
<style>
</style>
父组件调用
<template>
<div id="ops-region-wrapper">
<div class="ops-list-wrapper">
<table-vue :tableData="tableData" :showHeader="true" @showRegionFlag="showRegionFlag" @showDelDialog="showDelDialog"></table-vue>
<Pager :pages='pages' @changeCurrent='changeCurrent'></Pager>
</div>
</div>
</template>
<script>
import Pager from '@/components/Pager.vue';
import tableVue from './components/table.vue';
export default {
components:{
Pager,
tableVue
},
data() {
return {
tableData: [{
name: "Lucy",
age: 18,
mobile: "11111111111",
type: 1,
friends:[{
name: "Lucy-friend1"，
age: 16,
mobile: "11111111111"
},{
name: "Lucy-friend2"，
age: 16,
mobile: "11111111111"
}]
}],
pages: {//分页
showItem: 15,
total: 0,
currentPage: 1
},
}
},
methods: {
//分页
changeCurrent(val) {
this.pages.currentPage = val;
}
},
mounted() {
this.getList();
}
}
</script>
<style lang="scss">
