vue el-table实现递归嵌套的示例代码
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"> #ops-region-wrapper{ .el-table { margin-top: 15px; tr .el-table__expanded-cell { padding: 0; border-bottom: none; } .el-table__expand-icon { width: 18px; height: 18px; line-height: 16px; background: rgba(54, 134, 255, 0.2); color: #3686ff; border: 1px solid #3686FF; box-sizing: border-box; border-radius: 50%; transform: scale(0.8); i { font-weight: bold; font-size: 12px; left: 48%; } } .el-table__expand-icon--expanded{ transform: rotate(90deg) scale(0.8); } .hide-expand .el-table__expand-column>.cell { display: none; } } .in-table{ &::before{ border: none; } margin: 0; padding: 0; .el-table__expand-column>.cell,.el-table__expanded-cell { display: none; } } .el-button--text { margin: 0 20px 0 0; @include pageFont(12px, #006EFF, 400, "PingFangSC-Regular, PingFang SC", 17px); &.is-disabled{ color: #979797; } } .is-click { cursor: pointer; text-decoration: underline; text-decoration-color: #3686FF; @include pageFont(12px, #3686FF, 400, "PingFangSC-Regular, PingFang SC", 17px); } } </style>
