Sortable Columns (for users)

• added #19 and #18 — thanks @arenddeboer. Things brings the same amazing sorting functionality to user fields

Sortable columns

You can now sort columns based on custom field data...

So here's the catch: WordPress can only sort on things accessible to WP_Query (like a meta key). BUT if you're sorting on a meta key, awesome! just add this code..

Jigsaw::sort_column($post_types, $label, $meta_key, $numeric);

For example...

Jigsaw::sort_column('book', 'ISBN', 'isbn', true);
Jigsaw::sort_column('post', 'Location', 'location_name');
