Creating action button in a view

Dear support,

I’m using WP Data Tables and I’ve created a view for our interns where they can see all the upcoming activities, generated from our clients appointments tables.

I’ve also created a separate table to record our intern enrollment.

I would like to add for each row in the view two buttons “enroll” and “leave” that modify the second table inserting a row with the appointment id (equal to the row appointment id), user id (taken from wordpress) as the intern id, creation date (it’s actually default from timestamp), status (enroll / leave), modification date (already set as an update trigger in the database).

I’ve tried to do it using projects and browsed all the WP Data Access option but I’ve not found a way, do you have any idea of how can I do it?
