SQL table editor - Read only column

Hi

Does anyone know if it is possible to create a 'Read only' column in a SQL table editor?

I have set the column format 'AllowUpdates = False' which almost gives the correct functionality. However, the field is still editable when you insert a new row.

I currently get around this by completely ignoring the value in the field during the SQL Table Editor Save Data Event, but I wondered if it is was possible to ensure that it never appear editable to the user?

Regards,

Mark
