Html 如何使用tr标签内的两个ngFor循环？

我附上了视图的图像。我想迭代tr标记内的两个ngfor循环。我在tr中使用了div标签，但它在标签旁边循环按钮。我想在文件表头（请参阅图像文件的理解）

表节： 这是我的HTML页面的表格部分

您可以使用

ng模板

语法

有关更多信息：

{{cattype.Name}
{{manage.CreatedBy}}
{{manage.CreatedDate}
{{manage.DocumentDetails.DocName}

尝试将NgFor放入InvalidPipeArgument:“[object object]”对于管道“AsyncPipe”，我收到此错误您需要将管道导入模块，或删除管道。请参见此处InvalidPipeArgument:“[object object]”对于管道“AsyncPipe”，我收到此错误。您需要将管道导入模块，或删除管道。看这里
