需求
要做出如下图所示的 树形表格，也就是数据之间有父子类关系的这种，可以点击展开、收缩
像上图这样的表格树
实现
1.使用树形组件
在学习树形表格之前，肯定得先搞懂普通的树形组件是怎么搞的，然后将其套到表格中就好了，请参考ElementUI官方文档中的使用方法
链接：组件 | Element
基础用法展示
也就是数据中要有 children 作为树形组件中的 子数据
学会使用普通的树形结构之后，我们再来看 怎么使用树形的表格
2.使用树形表格
下面这段话出自博客：Element-ui 表格实现树形结构表格_elementui树形表格_在奋斗的大道的博客-CSDN博客
在el-table中，支持树类型的数据的显示。当 row 中包含 children 字段时，被视为树形数据。
渲染树形数据时，必须要指定 row-key。支持子节点数据异步加载。
通过指定 row 中的 hasChildren 字段来指定哪些行是包含子节点。children 与 hasChildren 都可以通过 tree-props 配置。
row-key="id"和:tree-props="{children: 'children', hasChildren: 'hasChildren'}是必须的。
数据表格区代码
<!-- 表格数据区-->
<el-table
v-if="refreshTable"
v-loading="loading"
:data="deptList"
row-key="id"
:default-expand-all="isExpandAll"
:tree-props="{children: 'children', hasChildren: 'hasChildren'}"
>
<el-table-column prop="deptName" label="部门名称" width="260"></el-table-column>
<el-table-column prop="orderNum" label="排序" width="200"></el-table-column>
......
......
......
</el-table>数据的格式
数据必须要有 children，例如下面的代码，就是树形表格数据的地方，我们伪造了一点数据，也是可以展示的。
// 表格树数据
deptList: [
{
id: "1",
deptName: "若依科技",
deptStatus: 1,
superiorId: "0",
orderNum: 1,
ancestors: "0",
createTime: "2023-07-18 08:49:56",
leaderId: "1678651668064612354",
children: [{
id: "1",
deptName: "若依科技",
deptStatus: 1,
superiorId: "0",
orderNum: 1,
ancestors: "0",
createTime: "2023-07-18 08:49:56",
leaderId: "1678651668064612354",
}]
},
],伪造的代码 的效果如下图

后端返回代码格式
我们项目中返回的数据是下面代码，只需要将后端返回的data 与前端的表格绑定即可
