The Created By field type will automatically display the name of the collaborator who originally created the record. 

How does it work?

1. From the list of field types, select the Created By option.
2. Each record of the table now displays the names of those who created it initially. 
   

The Created By field automatically updates with the creator's name each time you add a new record. 

Note: This is a fixed field type, and its content cannot be changed since the creator of a record remains the same forever.
