效果:
表格展开行官网使用:
通过设置 type="expand" 和 Scoped slot 可以开启展开行功能,el-table-column
的模板会被渲染成为展开行的内容,展开行可访问的属性与使用自定义列模板时的 Scoped slot
相同。
但是这种方法是有局限性,只是点击箭头展开,点击行没反应,这里做优化点击行也可以进行展开。
关键点(以下属性和事件缺一不可):
:row-key="getRowKeys"
:expand-row-keys="expands"
@row-click="clickRowHandle"
需要默认展开行只需要在expands存入需要展开行的id就可以了
