Not sure I fully follow you, but if I understand right, i would use a Deck view to show Table1, and define an Action attached to the “app name” column that uses LINKTOAPP expression.
You can the set the “if this condition is true” expression in the Action, to only display for records where Col4 email = AND([Col3] = useremail(), [Col4] = “OK”).
My syntax may not be completely correct for your case, but hopefully you get the idea. App Column Type (Deep Link) help.appsheet.com
