The default can be a lambda, but I don't think it can take any arguments (e.g., the row or row id), so instead you would probably have to use a computed field. Note, if you also want to be able to write your own values to the computed field, you can do that too -- it only calculates the computed value when no value is given. By default, computed fields are not shown in SQLFORMs, but you can override that by explicitly listing the fields to be included in the form.
