Drop-down menu with the data

[Cannone_Cannone]

Hello to all
in a table “1” I have a gate column.
in another table “2” I have a Gate column with data that I use as a database.
I would like that in the gate column of table “1” there was a drop-down menu with the data of the Gate column of table “2”
I professed to make a reference but the names of the tables are different so it doesn’t work.

Simple version is if you read data dynamically with a formula like Table2[Gate] in “Valid If” option.

Thank you.
Can I read two columns ?
Example table 2 has gate column, phone numbers
