Hi Marco,

Thank you for your purchase
Sorry for the delay in our responses, has been national holidays in our country for the last two days.

Well we don't have this built-in function, but you can try it next but you will need some experience with writing SQL queries and using WP hooks.

You can create a table with a query for example

SELECT 
user_id, 
user_name, 
user_address,
CONCAT('<a href="http:/yoursite.com/your_custom_page?user_id=',user_id,'">Details</a>') AS Details
FROM your_table_name

and then on your_custom_page, you will insert a shortcode of the tableID that you need with a placeholder like this

[wpdatatable id=1 var1=1]

of course, you will create that second table from a query like

SELECT * FROM second_table WHERE user_id = %VAR1%

and then you will use our hook for dynamic upsetting placeholders(you will insert this in functions.php file of your theme or child theme)

function updateVAR1($tableID){
  global $wdtVar1;
      //check is set GET parametar user_id
    if(isset($_GET['user_id'])){
        //get value from form fieald
        $wdtVar1 = $_GET['user_id'];
    }
  }
add_action('wpdatatables_before_get_table_metadata', 'updateVAR1');

Like this, I believe you will get a result as you need

If you don't have an SQL table, then there is also a workaround but with our add-on Master-detail and some hooks.

Let me know if you are interested in this.
