Describe the bug

Hi,

I am passing a custom formatter for the Details page like this:

# field1 is a dictionary
column_formatters_detail = {"column1": lambda m, a: json.dumps(m.field1, indent=4)}

However, when I go to the details page that formatting (pretty json) is not there, it still appears as a single json line. Is this a bug? How can I correct this without having to alter the templates? (no html). Is it possible to do it with WTForms?
