Refactor code for columns

[SilviaAmAm]

The following views have to display a table of zaken with similar columns:

• Record manager - destruction list create view. The zaken are fetched from the fetch-zaken endpoint and the front end (React) extracts the info and displays the columns
• Record manager - destruction list detail view. The zaken are fetched from the fetch-zaken endpoint and the front end (React) extracts the info and displays the columns
• Record manager - no archive date view. The zaken are fetched from the fetch-zaken endpoint and the front end (React) extracts the info and displays the columns
• Reviewer - detail view. The zaken are fetched from the fetch-zaken endpoint and the front end (React) extracts the info and displays the columns
• Destruction report. The columns are specified in a django template
• Excel export of zaken without archive date. The columns are specified in a python function.

It would be nice to refactor the code to avoid all these separate specification of the columns.
