@Steven_Cornelis the idea of providing more granular permissions to objects in a doc is something that our team is actively researching and there have been a number of threads and requests in the community on that topic, for example Granular Permissions and Share just one single page?.
We don’t currently offer a great solution to that problem. If privacy is not a concern, you can of course share a link to that row. Or explore options that might involve cross-doc’ing the relevant data in another doc.
