Hi Rafal

Thank you for reaching out to us.

You can link data to specific users with our plugin. To do this the table needs to be editable (so you would need to import the file, to create a manual table), and also you need to have the User ID field in the table. Meaning, if John has user ID = 5, when he logs into your WordPress site, and looks at the table, he'd only see his data if you selected the User ID column as the "User ID column" in the Editing tab above the table. If there's no user ID column, and they aren't logging into WordPress, this will not work.

You can enable the Show all rows in back-end option from the Editing tab of the table to see all entries in the back-end. You can also edit the table but if you edit the table as an administrator your User ID will be saved when you make the change so make sure to turn off the Users see and edit only own data option before editing.

You can have a look at this video for more information 

How to create editable tables in WordPress where users edit only own rows - wpDataTables 2.0

You can add image columns or attachment columns, which would allow you to upload files to a table, and you can use URL Link columns which would allow you to create hyperlinks or buttons.

Another way of adding hyperlinks is using the string-type columns, in combination with anchor tags.
