The EmptyMessage property in PrimeNG TreeTable is used to specify the message that is displayed when there are no records to display in the table.

To add an empty message to a TreeTable, you need to set the emptyMessage property to the message you want to display. For example:

In the above code, the emptyMessage property is set to "No records found", which will be displayed in the table if there is no data to show.

You can also bind the emptyMessage property to a variable in your component to give the user more context. For example:

In your component, you can define the emptyMsg property:

emptyMsg: string = "There are no records to display.";

This will display the message "There are no records to display." when there is no data to show in the TreeTable. 免责声明：本文内容通过AI工具匹配关键字智能整合而成，仅供参考，火山引擎不对内容的真实、准确或完整作任何形式的承诺。如有任何问题或意见，您可以通过联系service@volcengine.com进行反馈，火山引擎收到您的反馈后将及时答复和处理。
