el-table 树状表格查询符合条件的数据

需要对el-table的树状表格根据输入机构名称，筛选出符合条件的数据，可用如下方法：

页面内容如下： 

<el-input v-model="ogeName" placeholder="请输入机构名称"><el-table :data="list" row-key="id" :tree-props="{children:'children',hasChildren:'hasChildren'"><el-table-column label="机构名称" prop="attributes.org_name"></el-table-column>
</el-table>

数据格式如下：

   data() {return {data: [{attributes:[org_name:'1'],hasChildren: true,label: '一级 1',children: [{attributes:[org_name:'1'],hasChildren: true,label: '二级 1-1',children: [{attributes:[org_name:'1'],hasChildren: false,label: '三级 1-1-1'}]}]}],};},

具体筛选方法如下：

// 查询
handleSearch() {let list = this.listlet lastList = this.handleTreeData(list,this.orgName)this.list = lastList
}
// 筛选数据
handleTreeData(treeData,filterValue) {if (!treeData || treeData.length !== 0) {return []}const data = []for (let i = 0; i < treeData.length; i++) {let match = falsefor (const pro in treeDate[i]) {if (pro === 'label') {match |= treeData[i][pro].includes(filterValue)if (match) break}if (this.handleTreeData(treeData[i].children,filterValue).length > 0 || match) {data.push({ ...treeData[i],children: this.handleTreeData(treeData[i].children,filterValue})}return data
}
