如何解决如何在Dynamic Lightning：Datatable中修复URL字段，以使字段标签显示每个相关记录的名称？
我正在研究一个闪电组件，该组件将显示自定义，动态的“相关”记录列表，这些记录可用于在对象的列表中显示相关记录，该对象也是同一父级的子级。因此，例如，如果“帐户”是父记录，而“自定义对象1”和“自定义对象2”都是该帐户的子级，我想在“自定义对象1”上显示与同一帐户相关联的“自定义对象1”记录。自定义对象2闪电记录页面。我在LC画布和字段集中使用用户输入来分别定位记录和显示列。
我创建的组件的工作原理是可以查询并动态显示记录，列和字段值。我还想使用“名称”字段包含指向自定义对象1记录的可点击链接。但是，我似乎无法动态设置Name字段的typeAttribute以显示记录的标签。因为我将其分配为列标题的属性，所以它仅采用数组中的最后一个值。
是否可以将typeAttribute分配给记录响应，而不是列标题响应？
这是我的代码：

解决方法
我知道了。在基本级别上，此行缺少'fieldName'属性，该属性使用字段名称的API并应用值。
因此，这是：fieldSetResponse [i] ['typeAttributes'] = {label：arrayvalues [h] ['Name']}; 应该是这样的：fieldSetResponse [i] ['typeAttributes'] = {label：fieldName：{具有显示值的字段的API名称}};
即使如此，这也是不可能动态完成的，因为在这种情况下，当fieldName是查找字段本身时，它将显示记录ID。我可以传递一个硬编码的API名称，但是显然这会达到目的。
要解决此问题，我添加了一个通用标签（单击以查看记录），并在该目标对象上创建了一个公式字段，该公式字段拉入父记录名称并将其添加到我的字段集中。
这是一个已知问题：https://trailblazer.salesforce.com/ideaView?id=0873A000000lLXYQA2 这可以通过创建一个展平函数来解决（尽管我还没有尝试实现）：https://developer.salesforce.com/forums/?id=9062I000000XtwnQAC
