Add Issue Number to Article List

In case someone else needs this I found a solution:

function mbe_change_table_column_titles($columns){
	unset($columns['comments']);
    unset($columns['date']);// temporarily remove, to have custom column before date column
    $columns['issuem_issue_issue'] = 'Issue';
    $columns['date'] = 'Date';// readd the date column
    return $columns;
}
add_filter('manage_article_posts_columns', 'mbe_change_table_column_titles');

function mbe_change_column_rows($column_name, $post_id){
    if($column_name == 'issuem_issue_issue'){
        echo get_the_term_list($post_id, 'issuem_issue', '', ', ', '').PHP_EOL;
    }
}
add_action('manage_article_posts_custom_column', 'mbe_change_column_rows', 10, 2);

function mbe_change_sortable_columns($columns){
    $columns['issuem_issue_issue'] = 'issuem_issue_issue';
    return $columns;
}
add_filter('manage_edit-article_sortable_columns', 'mbe_change_sortable_columns');

function mbe_sort_custom_column($clauses, $wp_query){
    global $wpdb;
    if(isset($wp_query->query['orderby']) && $wp_query->query['orderby'] == 'issue'){
        $clauses['join'] .= <<<SQL
LEFT OUTER JOIN {$wpdb->term_relationships} ON {$wpdb->posts}.ID={$wpdb->term_relationships}.object_id
LEFT OUTER JOIN {$wpdb->term_taxonomy} USING (term_taxonomy_id)
LEFT OUTER JOIN {$wpdb->terms} USING (term_id)
SQL;
        $clauses['where'] .= "AND (taxonomy = 'issuem_issue' OR taxonomy IS NULL)";
        $clauses['groupby'] = "object_id";
        $clauses['orderby'] = "GROUP_CONCAT({$wpdb->terms}.name ORDER BY name ASC)";
        if(strtoupper($wp_query->get('order')) == 'ASC'){
            $clauses['orderby'] .= 'ASC';
        } else{
            $clauses['orderby'] .= 'DESC';
        }
    }
    return $clauses;
}
add_filter('posts_clauses', 'mbe_sort_custom_column', 10, 2);

function mbe_print_admin_styles(){
    global $pagenow;
    if($pagenow == 'edit.php' && isset($_GET['post_type']) && $_GET['post_type'] == 'article'){
        echo '
        <style type="text/css">
            .column-issuem_issue_issue{
                width: 10%;
            }
        </style>
        '.PHP_EOL;
    }
}
add_action('admin_print_styles', 'mbe_print_admin_styles');
