It would be nice adding some example on how to add terms from custom taxonomy. There is one:
Jigsaw::add_column($post_type, $column_label, function($post_id){
$term_list = wp_get_post_terms($post_id, $colum_slug, array("fields" => "all"));
if(count($term_list) > 1) {
foreach ($term_list as $term_single) {
echo $term_single->name . " ";
}
} else {
echo $term_list[0]->name;
}
}, 10);
Maybe also adding link term would be greater!
