我想在网格的下一行中显示一个嵌套的JSON对象。我正在使用Ember和mdc-layout-grid。

我的JSON数据如下：

data = [{
"amzOrderId": "403-8957866-2673902","financialEventType": "SHIPMENT","timestamp": 1570025882722,"numOfItems": 1,"nested": [{
"amzOrderId": "405-3430902-0842748","numOfItems": 1}]},{
"amzOrderId": "171-9021455-7043516","timestamp": 15700258888722,"nested":null,}]

我要渲染的hbs文件：

<li class="sales-list-row">
  {{#mdc-layout-grid as |grid|}}
    {{#grid.inner as |inner|}}
      {{#inner.cell class="bought" span=2}}
        <h3 class="bought__value">{{get data "numOfItems"}}</h3>
      {{/inner.cell}}
      {{#inner.cell class="purchased" span=2}}
        <span class="purchased__text">Purchased</span>
        <h3 class="purchased__value">{{format-date (get data "timestamp") "date"}}</h3>
      {{/inner.cell}}
      {{#inner.cell class="id" span=2}}
        <h4 class="id__value">{{get data "amzOrderId"}}</h4>
      {{/inner.cell}}        
    {{/grid.inner}}
  {{/mdc-layout-grid}}
</li>

现在，我想在下一行（如果存在）中渲染“嵌套的”对象值（如果嵌套为null，则移至下一个data [element]）。我该如何解决这个问题？我尝试了几种方法，但是它们不起作用。
