vue+element table实时数据不更新

Question

需求是做一个实时日志输出，每隔一秒查询一次接口，将返回的数据更新到表格中。
问题：从打印的日志看，的确是每秒都在push数据。但是表格数据不显示，我点击其他组件，数据会更新出来，更新后数据保持固定，再次点击再次更新，求问是哪里出了问题，是双向绑定的原因吗？
第一次加载页面效果：

点击其他按钮前：

点击后：

可以看到内容很多，是从加载页面后就一直在push数据，但是只有点击其他按钮才会更新数据

下面是代码

<template>
    <el-table :key="Math.random()" :data="tableData" ref="tableRef" style="width: 100%" max-height="500">
        <el-table-column prop="content">
            <template #header>
                运行状态：【runing】
                <el-button @click="emptyTable()" type="primary" size="small">清空</el-button>
            </template>
        </el-table-column>
    </el-table>
</template>

<script lang="ts" setup>
import { ref, nextTick } from 'vue';
const tableRef = ref(null);
interface Log {
    content: string;
}
//let cc: Array[Log] = [];
// for (let i = 0; i < 10; i++) {
//     let log: Log = {
//         content:
//             '2022-02-09 08:43:19.251 [http-nio-2005-exec-1] INFO  org.apache.catalina.core.ContainerBase.[Tomcat].[localhost].[/] Line:173 - Initializing Spring DispatcherServlet dispatcherServlet Initializing Spring DispatcherServlet dispatcherServletInitializing Spring DispatcherServlet dispatcherServletInitializing Spring DispatcherServlet dispatcherServletInitializing Spring DispatcherServlet dispatcherServletInitializing Spring DispatcherServlet dispatcherServlet',
//     };
//     cc.push(log);
// }
let tableData: Array[Log] = [];
let log: Log = {
    content:
        '2022-02-09 08:43:19.251 [http-nio-2005-exec-1] INFO  org.apache.catalina.core.ContainerBase.[Tomcat].[localhost].[/] Line:173 - Initializing Spring DispatcherServlet dispatcherServlet Initializing Spring DispatcherServlet dispatcherServletInitializing Spring DispatcherServlet dispatcherServletInitializing Spring DispatcherServlet dispatcherServletInitializing Spring DispatcherServlet dispatcherServletInitializing Spring DispatcherServlet dispatcherServlet',
};
window.setInterval(() => {
    setTimeout(() => {
        tableData.push(log);
        //console.log("hhh")
    }, 0);
}, 1000);

// let tableData: Array[Log] = [];
// for (let i in cc) {
//     tableData.push(cc[i]);
// }
// //渲染完成后的动作
// nextTick(() => {
//     //将滚动条默认至底部
//     tableRef.value.$refs.bodyWrapper.scrollTop = tableRef.value.$refs.bodyWrapper.scrollHeight;
// });

//清空表格内容
function emptyTable() {
    tableData = [];
}
</script>
