element ui 表格 点击某行折叠或展开 有数展示下拉图标
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: 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' } }, }, style中的内容: <style lang="scss"> .row-expand-cover .el-table__expand-icon { visibility: hidden; display: none; } .row-expand-show .el-table__cell { &:nth-child(2) .el-table__expand-icon { visibility: hidden; display: none; } } </style> |
