如何在ngx-datatable中传播数据？

Question

[
  {
    "id": "1231",
    "hero": "xys",
    "lastAddedDate": "2019-01-16",
    "movieDetails": [
      {
        "id": 1,
        "movie": "xasdas",
        "director": "jdnka",
        "release date": "2019-01-19 18:33:51.894"
      },
      {
        "id": 2,
        "movie": "zgh",
        "director": "Approved",
        "release date": "2019-01-19 18:33:51.894"
      }
    ]
  },
  {
    "id": "123",
    "hero": "xysz",
    "lastAddedDate": "2019-01-16",
    "movieDetails": [
      {
        "id": 1,
        "movie": "asdxasdasasd",
        "director": "asdfsjdnka",
        "release date": "2019-01-19 18:33:51.894"
      },
      {
        "id": 2,
        "movie": "zygtas",
        "director": "owq",
        "release date": "2019-01-19 18:33:51.894"
      }
    ]
  }
]

在此JSON中，我想使用ngxDatatable以表的形式散布所有数据。在这里，我面对着movieDetails数组。当我尝试填充表中的movieDetails时，它的值未定义。

这是我的表格的格式

Id | Hero | LastAddedDate | Movie1 | Movie1Director | Movie1ReleaseDate | Movie2 | Movie2Director | movie2ReleaseDate

|-列分隔符
