Limit users access on ref table

[Hong_Yaw_Kuang]

Dear all appsheet creators,

How do I limit data (main table and ref table) isolated within certain people than others?

What I could do now only main table, while I have a column with user email stated, so only same email login could access main table, but ref table doesn’t have this user email, other users can still see other details in ref table except ref column.

Any trick in solving this? Thank you very much
