wpdatatables plugin: Calculate and create 5 tables/queries

On a WordPress site the admins collect donations (handled by free givewp plugin). Now we need a more efficient way to display that data to users, plus additional calculations. For that reason we got the wpdatatables plugin. It has all features to display data from the database on the frontend. Experience with wpdatatables is greatly appreciated, but not a super strict requirement, as they also work with native SQL queries/language. We need: -> (2) Sum of donations from users (their own amount, along already saved data like Timestamp, etc..) All data is in db. Just need the queries to display in user account. -> few other simple to mediocre queries and calculations as stated in the doc (3) to (6) (3) (4) and (6) needs to be calculated based on the userdata in the wp db. (5) All data is already there.. just have it displayed in another form (list/table, instead of chart). Before bidding: Please read the doc and understand the requirements. I´m happily answering your questions.
