The Created by data type is for displaying a non-editable user value showing who created the row.

Created by cells generally default to the creator of the worksheet in a format similar to the User data type. However, if a different user adds a new row, Created by will reflect who added the row. The Created by data type is a System data type that restricts data in a column and automatically adds the corresponding data. 

Configuration Options

The Created by data type has no configuration options, as the data in cells cannot be changed. However, like other text data types, you can adjust the formatting of cells in a Created by column using the formatting toolbar.
