Formatter is useful for transforming columns with custom styling and for manipulating values.
With the Default Formatter, you can apply standard text formatting and make reference to a foreign table.
Quick Note
The same can be done using the Options Formatter too.

If you have a column that holds the foreign key value to another table, it is possible to make reference to it by configuring it in the Configure Foreign Key tab.
