在Angular中从Array of Array中显示对象名称

Question

我对如何在对象数组中显示categories.name感到困惑。我想在第一个td中显示。

<tr *ngFor="let innerItem of project.project_services">
    HERE--> <td>{{ innerItem.categories.[name]}</td>
    <td>{{innerItem.service.sku}}</td>
    <td>{{innerItem.service.name}}</td>
</tr>

Following insert queries happens inside a transaction and is run by each thread.
Thread_1 transaction query:
    randomUUID_1_1 = UUID.randomUUID()
    randomUUID_2_1 = UUID.randomUUID()
    Insert Into Table_A (row_id, product_id) VALUES (randomUUID_1_1, 'X');
    Insert Into Table_B (row_id, item_id, mapped_product_id) VALUES (randomUUID_2_1, randomUUID_1_1, 'Y'); 
Thread_2 separate transaction query:
    randomUUID_1_2 = UUID.randomUUID()
    randomUUID_2_2 = UUID.randomUUID()
    Insert Into Table_A (row_id, product_id) VALUES (randomUUID_1_2, 'X');
    Insert Into Table_B (row_id, item_id, mapped_product_id) VALUES (randomUUID_2_2, randomUUID_1_2, 'Y');
