To add new column coupon in woo-commerce order table and get all coupon code according to order. you need to copy and paste in you function.php.

add_filter('manage_edit-shop_order_columns', 'custom_shop_order_column', 11);

function custom_shop_order_column($columns) {
    //add columns
    $columns['my-column1'] = __('Coupons Code', 'theme_slug');
    return $columns;
}

// adding the data for each orders by column (example)
add_action('manage_shop_order_posts_custom_column', 'cbsp_credit_details', 10, 2);

function cbsp_credit_details($column) {
    global $post, $woocommerce, $the_order;
    $order_id = $the_order->id;

    switch ($column) {
        case 'my-column1' :
            // $myVarOne = wc_get_order_item_meta( $order_id, 15, true );
            if ($the_order->get_used_coupons()) {

                $coupons_count = count($the_order->get_used_coupons());
                foreach ($the_order->get_used_coupons() as $coupon) {
                    echo $coupon;

                    $i++;
                }

                echo '
';
            }
           // echo $myVarOne;
            break;
    }
}
