PHP通过分组遍历数据和打印部分

Question

所以我有以下查询：

$sections = Section::with(['subsections.tasks.companies'])
    ->where('parent', NULL)
    ->sorted()
    ->get()
    ->toArray();

这将返回以下类型的结构：

array:2 [▼
  0 => array:10 [▼
    "id" => 12
    "name" => "Chapter 1"
    "parent" => null
    "position" => 12
    "created_at" => "2018-05-10 16:43:04"
    "updated_at" => "2018-06-08 14:37:54"
    "completed" => false
    "subsections" => array:2 [▼
      0 => array:10 [▼
        "id" => 14
        "name" => "Subcatgeory 2"
        "parent" => 12
        "created_at" => "2018-05-10 16:52:28"
        "updated_at" => "2018-06-08 14:37:51"
        "completed" => false
        "tasks" => array:1 [▼
          0 => array:15 [▼
            "id" => 3
            "name" => "Another task"
            "active" => 1
            "created_at" => "2018-05-10 16:52:50"
            "updated_at" => "2018-05-14 09:33:32"
            "pivot" => array:2 [▶]
            "companies" => []
          ]
        ]
      ]
      1 => array:10 [▶]
    ]
  ]
  1 => array:10 [▶]
]

基本上是“部分”>“子部分”>“任务”。

然后我尝试将这些数据导出到html表中，但是我想按如下所示的任务节对数据进行分组：

stage1是外部父节的名称。

我设法在视图文件中打印出父节：

<table class="table table-bordered">

    <tbody>
    <tr>
        <td>Customer</td>
        @foreach($sections as $section)
            <td>{{ $section->name }}</td>
        @endforeach
    </tr>

    <tr>
        <th></th>
        <th>Task 1</th>
        <th>Task 2</th>
        <th>Task 3</th>
        <th>Task 4</th>
    </tr>
    <tbody>

    <tr>
        <td></td>
        <td>Date time</td>
        <td>Date time</td>
        <td>Date time</td>
        <td>Date time</td>
    </tr>

    </tbody>
</table>

但是我要通过按上述屏幕快照中的任务进行分组来打印数据，因为我必须停留在主循环中，但必须突破<tr>标记。谁能帮助我实现这一目标？
