Hi @KMW ,
Could you share the details of configuring Add a row into a table action?
I did a simple test using this action and didn't see a similar issue.
Please try to update or re-create the connection for this action.

Please take a try and feel free let me know if issue still exist.

Edit: I am the owner of the SharePoint library where the Excel file is saved (and of the connected Office 365-group). The Excel file has a table defined.
Here is a screenshot of a simple test flow I made to reproduce the error:
