Vue中使用el-table :data数据更新,但表格不显示

结论：我写的tableData没加reactive
顺便放上尝试过的几个方法：
增加key属性
也是增加key
安装版本更低的element-plus
其他方法

<template>
    <el-table :data="tableData" @change="console.log('changed',tableData);">
        <el-table-column prop="area" label="area"></el-table-column>
        <el-table-column prop="date" label="date"></el-table-column>
        <el-table-column prop="dayForecast" label="dayForecast"></el-table-column>
    </el-table>

</template>

<script setup name="Model" lang="ts">
import axios from 'axios';
import { reactive } from 'vue';
const tableData = reactive([])
async function getData() {
    try {
        const promise1 = await axios({url: 'http://hmajax.itheima.net/api/weather', params: {city: '110100'}})
        tableData.push({
            area: promise1.data.data.area,
            date: promise1.data.data.date,
            dayForecast: promise1.data.data.dayForecast[0].weather,
        })       
        const promise2 = await axios({url: 'http://hmajax.itheima.net/api/weather', params: {city: '310100'}})
        tableData.push({
            area: promise2.data.data.area,
            date: promise2.data.data.date,
