Maybe someone can save me today. Missing database tables/columns no migrations.

Well if you do not have a backup then you are out of luck and less you can
find someone that has the CodeIgniter App and they are willing to give you
the tables

Which you did not say what app it was.

What did you Try? What did you Get? What did you Expect?
