Hello Alvin

I am sorry to disappoint you, but unfortunately something like this is not possible with the plugin's built-in features.

Can you please explain in a bit more detail (and with an example, preferably) what you're trying to achieve?

Thanks for your assistance here, Axel

I did forward a different advice to Alvin, here, in a private response. I'll post it again publically, in case anyone needs it:

You may have a use of using dynamic query with placeholders here.

You do need some experience with writing SQL queries and using WP hooks.

If you have a 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');
