Both column formatting and SharePoint Framework Field Customizer extensions enable you to customize how fields in SharePoint lists are displayed. The Field Customizer is more powerful because you can use it to write any code that you want to control how a field is displayed.
Column formatting is more easily and broadly applied. However, it is less flexible, because it does not allow for custom code; it only allows for certain predefined elements and attributes.
The following table compares column formatting and the Field Customizer.

I have a SharePoint calendar, with a little over a dozen columns (I have also added a couple extra columns). When adding/editing calendar events, I notice that the Attendance column is not showing up as a field. If I look in SP Designer, I see the column, Attendance, but it shows a blank Content Type (whereas most all the other columns have a Content Type of Event). Can someone please talk me through this? Not only do I need the Attendance column to be a field for a calendar event, but I have the same calendar on many other sites, so hopefully I can update the Content Type for the Attendance column to Event and solve my problem. Please advise.
Go to List Settings and click on Event in the Content Type section. Then click on “Add from existing site or list columns”. Choose Attendee from the list columns and click on Add.
You can also select “use this calendar to share member’s schedule” in List Settings/Title, Description and Navigation. A new content type “Schedule” will be added , which contains the Attendee field.
