| 有个需求是一个列表，里面包含多个单子，每个单子可以是唯一，也可以是多个合并之后的，而且每个单子下面显示的是另外一个表格，来上图 
每行的操作还不一样，然后通过官网的一些例子总结了一下合并代码 <template> <div class="app-container"> <div> <el-table :data="tableData" style="width: 100%;margin-bottom: 20px;" :span-method="arraySpanMethod" row-key="id" border > <el-table-column type="expand"> <template slot-scope="props"> <el-table class="table-in-table" :show-header="false" :data="props.row.datas" style="width: 100%;" row-key="id" :span-method="arraySpanMethod" border > <el-table-column type="expand"> <template slot-scope="props"> <el-table class="table-in-table" :data="props.row.datas" style="width: 100%;" row-key="id" border > <el-table-column prop="date" label="下单日期" width="180"></el-table-column> <el-table-column prop="type" label="单据类型" width="180"></el-table-column> <el-table-column prop="status" label="状态"></el-table-column> <el-table-column label="操作" width="120"> <template slot-scope="props"> <el-button type="text" size="small">移除</el-button> </template> </el-table-column> </el-table> </template> </el-table-column> <el-table-column prop="applyNo" label="申请单号" width="132.2"></el-table-column> <el-table-column prop="name" label="姓名" width="180"></el-table-column> <el-table-column prop="address" label="地址"></el-table-column> </el-table> </template> </el-table-column> <el-table-column prop="applyNo" label="申请单号" width="180"></el-table-column> <el-table-column prop="name" label="姓名" width="180"></el-table-column> <el-table-column prop="address" label="地址"></el-table-column> <el-table-column label="操作" width="120"> <template slot-scope="props"> <el-button type="text" size="small">移除</el-button> </template> </el-table-column> </el-table> </div> </div></template> <script>export default { name: "name1", components: {}, data() { return { tableData: [ { id: 1, applyNo: "202004291234", name: "李四", address: "上海市普陀区金沙江路 1518 弄" }, { id: 2, applyNo: "202004291235", name: "张三", address: "上海市普陀区金沙江路 1517 弄" }, { id: 3, applyNo: "202004291236,202004291237", name: "王五", address: "上海市普陀区金沙江路 1519 弄", datas: [ { id: 31, applyNo: "202004291236", name: "王五", address: "上海市普陀区金沙江路 1519 弄", datas: [ { id: 31, date: "2016-05-01", type: "类型1", status: "已发货" }, { id: 32, date: "2016-05-01", type: "类型2", status: "未发货" } ] }, { id: 32, applyNo: "202004291237", name: "王五", address: "上海市普陀区金沙江路 1519 弄" } ] }, { id: 4, applyNo: "202004291238", name: "赵6六", address: "上海市普陀区金沙江路 1516 弄" } ] }; }, methods: { arraySpanMethod({ row, column, rowIndex, columnIndex }) { if (!row.datas) { if (columnIndex === 0) { return [0, 0]; } else if (columnIndex === 1) { return [1, 2]; } } } }};</script><style lang="scss" scoped>.app-container { ::v-deep { .el-table th { background: #ddeeff; } .el-table__expanded-cell { border-bottom: 0px; border-right: 0px; padding: 0px 0px 0px 47px; } } .table-in-table { border-top: 0px; }}</style>注：需要注意一点的是，这里面的孩子节点不能用children，因为官方默认是children，所以会出现别的下拉组件
设置td宽度的时候，需要注意的是里面跟外层的差47.8 到此这篇关于element table多层嵌套显示的实践的文章就介绍到这了,更多相关element table多层嵌套内容请搜索51zixue.net以前的文章或继续浏览下面的相关文章希望大家以后多多支持51zixue.net！
