Hi Paul,

Thank you for your purchase.

Well we dont have this built in function, but you can try next but you will need some experiance with writing SQL queries and using WP hooks.

You can create table with 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 shortcode of the tableid that you need with placeholder like this

[wpdatatable id=1 var1=1]

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

SELECT * FROM second_table WHERE user_id = %VAR1%

and then you will use our hook for dynamic upsetting placeholders

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 result like you need
