实现的效果是这样的
这是表格demo
<el-table :data="tableData" style="width: 100%;margin-bottom: 20px;" :row-class-name="getRowClassName" @row-click="rowClick" :row-key="rowKey" :expand-row-keys="nowExpand">
<el-table-column type="expand">
<template slot-scope="props" v-if="props.row.children">
<el-form style="width: 100%;">
<el-form-item>
<el-table style="width: 100%;background: none" :data="props.row.children">
<el-table-column label="日期" prop="date" align="center">
</el-table-column>
<el-table-column label="姓名" prop="name" align="center">
</el-table-column>
<el-table-column label="地址" prop="address" align="center">
</el-table-column>
<el-table-column label="操作" align="center">
<template slot-scope="scope">
<el-button size="mini" @click="handleEdit(scope.$index, scope.row)" type="primary" plain>详情</el-button>
<el-button size="mini" type="success" @click="handleDelete(scope.$index, scope.row)" plain>录入</el-button>
</template>
</el-table-column>
</el-table>
</el-form-item>
</el-form>
</template>
</el-table-column>
<el-table-column prop="date" label="日期" align="center">
</el-table-column>
<el-table-column prop="name" label="姓名" align="center">
</el-table-column>
<el-table-column prop="address" label="地址" align="center">
</el-table-column>
</el-table>
这是data中的数据
data(){
return{
//当前展开行
nowExpand: [],
//表格数据
tableData: [{
id: 1,
date: '2016-05-02',
name: '王小虎',
address: '上海市普陀区金沙江路 1518 弄'
}, {
id: 2,
date: '2016-05-04',
name: '王小虎',
address: '上海市普陀区金沙江路 1517 弄'
}, {
id: 3,
date: '2016-05-01',
name: '王小虎',
address: '上海市普陀区金沙江路 1519 弄',
children: [{
id: 31,
date: '2016-05-01',
name: '王小虎',
address: '上海市普陀区金沙江路 1519 弄'
}, {
id: 32,
date: '2016-05-01',
name: '王小虎',
address: '上海市普陀区金沙江路 1519 弄'
}]
}, {
id: 4,
date: '2016-05-03',
name: '王小虎',
address: '上海市普陀区金沙江路 1516 弄'
}],}
}
这是方法文章来源:https://www.toymoban.com/news/detail-513461.html
methods: {
//rowkey获取方式
rowKey(row) {
return row.id
},
//点击该行就添加到显示数组中
rowClick(row, event, column) {
if (row.children != null) {
let index = this.nowExpand.indexOf(row.id)
if (index == -1) {
this.nowExpand.push(row.id)
} else {
this.nowExpand.splice(index, 1)
}
}
},
//设置没行的样式名称 是否显示下拉箭头
getRowClassName({ row, rowIndex }) {//有children就显示箭头
if (!row.children) {
return 'row-expand-cover';
} else {
return 'row-expand-show'
}
},
},
