如何使用typescripts解析嵌套的json对象数组并在primeng组件中显示它

Question

我是Angular js的新手。有一个任务是使用typescripts解析嵌套的json对象数组并在primeng表中显示它。 Primeng绝对是新的。我能够显示平面结构json，但是这个嵌套的对象数组正在产生问题。

我需要在一些主 - 细节关系中展示它。

以下是JSON结构：

[

    "status": "Pending",

        }
    ],

        "modificationDate": "2027-10-20T16:00:00Z",
        "isCurrent": true
    }
}
]

请使用上面的json帮我创建一个带有primeng的角度项目。感谢快速帮助。
