In other words I'm looking for a datatable plugin or js library which works for wp-admin/edit.php (admin >>> all posts page). Not for post writing page. Do you know any plugin that works as datatable? If you know and write I will be pleased. Thank you.
Hi, I've just found this one: https://wordpress.org/plugins/codepress-admin-columns/ and this one: https://wordpress.org/plugins/posts-data-table/ Is this something you are looking for?
A thing of higher level than yours. Better learn to eat McDonalds burger properly as running this kind of business might sometimes put people into bad loans.
