Combine Datatable Column For display Link

Question

I am using customized SSP class from github repo

Its working fine as expected. I want display a link in my column like below

<a href="https://example.com/vendors/view/'.$d.'">Vendor Name</a>

But I want use vendor id in href and vendor name as link name But in SSP class, I do not know how I can combine two column data to show link.

$columns = array(
    
    array( 'db' => '`e`.`error_time`', 'dt' => 0, 'field' => 'error_time', 
    'formatter' => function( $d, $row ) {
        $time = time_elapsed_string($d,SERVER_TIMEZONE);
        return $time;
    }),
    
    array( 'db' => '`v`.`vendor_name`', 'dt' => 1, 'field' => 'vendor_name' ),
    array( 'db' => '`e`.`error_vendor`', 'dt' => 2, 'field' => 'error_vendor', 
    'formatter' => function( $d, $row ) {
        $link = '<a href="https://example.com/vendors/view/'.$d.'">Vendor Name</a>';
        return $link;
    }),
    array( 'db' => '`e`.`error_details`', 'dt' => 3, 'field' => 'error_details' ),
    array( 'db' => '`e`.`error_action`', 'dt' => 4, 'field' => 'error_action' )
    
);

For achieve my goal, I need two column data in one called dt1 and dt2. I am little new in PHP and does not know what actually I can do for solve the puzzle. Let me know if someone here can help me for do it.

Thanks!
