el-table 懒加载，后端传了整体list带children，前端如何自行去处理

首先html中调用el-table组件需要注意

在这里插入代码片
 <el-table :data="tableData" v-loading="loading" row-key="id" ref="table"
  :lazy="true"
  :load="loads"
  :tree-props="{ children: 'children', hasChildren: 'hasChildren' }"
  @expand-change="handleExpandChange" 。。。。

其次在data()中放入属性

 copyData: [], //赋值拷贝数据
  maps: new Map(), //用于存储 子节点懒加载的数据
  copymaps: new Map(), 
  doSelect: {
   
    id: null, title: "" }, //子节点懒加载对应的节点

meth() 中

getList() {
   
   
  this.loading = true;
  // 执行查询
  getPage(this.queryParams).then((response) => {
   
   
    this.list = response.data;
    this.copyData = JSON.parse(JSON.stringify(response.data));
    this.tableData = this.list;
    this.tableData.map((item) => {
   
   
      item.hasChildren = item.children && item.children.length > 0;
      item.idList = [item.id];
      item.children = null;
      return item;
    });
    console.log(this.tableData);
    this.$nextTick(() => {
   
   
      this.refreshRow();
    });
    this.loading = false;
  });
},

```kotlin
loads(tree, treeNode, resolve) {
   
   
      const pid = tree.id;
