Description
For Views that use Table format. Adds a row underneath each record - you change the format from 'table' to the 'secondary row' option, you get an extra select dropdown in the table *settings*, and you can also specify colspan. This does mean the label will be missing by default (you won't have a column header any more) - so you need to edit the field and tick rewrite output, and then specify your desired label, followed by the field value in Twig.
