小编sam*_*ara的帖子

我有这样的数组，

[[{"user":"1","nice":"0","sys":"1","CPU":"93","irq":"0"}, 
{"user":"1","nice":"0","sys":"1","CPU":"92","irq":"0"}, 
{"user":"1","nice":"0","sys":"1","CPU":"92","irq":"0"}, 
{"user":"1","nice":"0","sys":"1","CPU":"92","irq":"0"}], 
[{"user":"0","nice":"0","sys":"0","CPU":"91","irq":"0"}, 
{"user":"0","nice":"0","sys":"1","CPU":"91","irq":"0"}, 
{"user":"1","nice":"0","sys":"0","CPU":"91","irq":"0"}, 
{"user":"0","nice":"0","sys":"0","CPU":"90","irq":"0"}]]

我想使用 ngFor 循环遍历 HTML 表中的这个对象数组

<table class="table table-striped mt-5">
  <thead>
    <tr>
      <th scope="col">User</th>
      <th scope="col">Nice</th>
      <th scope="col">Sys</th>
      <th scope="col">CPU</th>
      <th scope="col">IRQ</th>
    </tr>
  </thead>
  <tbody>
    <tr *ngFor="let post of posts">
      <td>{{post.user}}</td>
      <td>{{post.nice}}</td>
      <td>{{post.sys}}</td>
      <td>{{post.CPU}}</td>
      <td>{{post.irq}}</td>
    </tr>
  </tbody>
</table>

但我的代码不起作用
