The title says it all.
I’ve been taking WP_LIST_AUTHOR and modifying it to create more of a member directory than just a list of authors while leaving a lot of the original options intact (and I am going to add more down the line). My first task was to build pagination into it, which I managed to do successfully (code below) [although it’s not very pretty yet].
I now want it to build this information into tables (probably 15 results per page, in a 3×5 grid. Row – cell cell cell Row – cell cell cell etc). I am not really sure on the best way to do this, or if this can even be done with the current way the code is constructed, any advice or linked resources would be greatly appreciated! I’m really just hacking things together 😉 Also note; the site uses s2member plugin and any code will need to not mess with that functionality.

Your snippet is a little too verbose to follow (and it’s late here) so this is more of an alternate take. I think that forking wp_list_author() might be overkill here. It would be more elegant to hook inside user search and accurately slice the portion of authors you need.
Here is some example code I came up with:
add_action('pre_user_query','offset_authors');
$authors_per_page = 1;
$current_page = absint(get_query_var('page'));
function offset_authors( $query ) {
global $current_page, $authors_per_page;
$offset = empty($current_page) ? 0 : ($current_page - 1) * $authors_per_page;
$query->query_limit = "LIMIT {$offset},{$authors_per_page}";
}
wp_list_authors();
Also check out paginate_links() function for building pagination.
