vue表格引用的数据源时发生了一个奇怪的问题，急，求解？
如图，获得的数据是国内疫情表，包括省份总的疫情信息和嵌套在省内的各区域的疫情信息，我想提取省名，但发现
把各城市名的都提出来了，请问该如何解决？请赐教，不胜感激。

此为vue文件
下为vue.config.js文件
const vueConfig = {
lintOnSave: false,

// development server port 8000
port: 8000,
proxy: {
"/proxy/": {//以/proxy/为开头的适合这个规则
target:"https://view.inews.qq.com",
// target: "https://interface.sina.cn",//目标地址
"secure": true,//false为http访问，true为https访问
"changeOrigin": true,//跨域访问设置，true代表跨域
"pathRewrite": {//路径改写规则
"^/proxy": ""//以/proxy/为开头的改写为''
//下面这种也行
// "^/api":"/list"//以/api/为开头的改写为'/list'
},
// "headers": {//设置请求头伪装成手机端的访问

}
module.exports = vueConfig
回答：
表格支持树形数据的展示，当数据中有 children 字段时会自动展示为树形表格，如果不需要或配置为其他字段可以用 childrenColumnName 进行配置
<a-table :columns="dangerousPlaceColumns" childrenColumnName="someWords"
:data-source="dangerousPlace"
:pagination="pagination"
@change="handleTableChange"
:rowKey="record=>record.name"
:style="{padding:'10px 0px',margin:'0px',textAlign:'center'}"
