Thanks for the kind review. The plugin doesn’t have any styling options because I didn’t want to impose any sort of styles/layout on the user. It is meant to be fully customizable, however, and I’m relatively certain that you can transform the output into a table.
While a full solution would be beyond the level of support I provide here, you’d probably only need to open and close the table on the simple_user_listing_before_loop
and simple_user_listing_after_loop
hooks and then override the content-author.php
template in your theme to be a table row.
