Is your feature request related to a problem? Please describe.

When developing workflows with Nextcloud Flow and Tables, there's always the need for pretty complex filters since the values of a row are returned as array.

Describe the solution you'd like

Values should be returned as JSON fields. It might also be beneficial to allow the user to add a technical name to a column, which is then the field name in the json.

Describe alternatives you've considered

Using the filters, but that results in pretty complex data extraction (working with column IDs and filters)
