Hello,

Thank you for reaching out to us!

If a group has been given the reader role, then all users within that group essentially inherit that role as well. So they should be able to view the table you're referring to.

Could you provide some more context?

1. Did a user that was a part of that group mention that they were not able to see the data or did you impersonate them?
2. Are you positive that the user in question is a part of that group? (Just to double check)
3. If you were to impersonate the group itself, can you see the data?
4. What kind of table are you working with? Is it the result of a query, list, dataset, etc...
