我对如何读取这些数组和对象中的 project.name 感到困惑？我想显示project.name，构建project.description。小的...？如何在html表格行中迭代它？这是我在下面所做的。希望大家能帮忙

我认为您需要将其更改为：

<tr *ngFor="let project of projects">
 <td *ngFor="let inner of project.organization.projects">{{ inner.name }}</td>
</tr>

先循环项目，获取每个项目的组织，从组织中循环内部项目，获取名称

您的迭代应如下所示：

<table>
  <ng-container *ngFor="let project of projects.projects"> 
    <tr>
      <th>Name</th>
      <th>Description</th>
    </tr>
    <tr *ngFor="let inner of project.organization.projects">
      <td>{{inner.name}}</td>
      <td>{{inner.description}}
    </tr>
  </ng-container> 
</table>
