   Add Columns

   Suppose you have a ‘books’ custom post type and you want to add the publisher and book author to the list of columns.

   add_filter('manage_books_posts_columns' , 'book_cpt_columns');
   
   function book_cpt_columns($columns) {
   	$new_columns = array(
   		'publisher' => __('Publisher', 'ThemeName'),
   		'book_author' => __('Book Author', 'ThemeName'),
   	);
   
       return array_merge($columns, $new_columns);
   }

   Replace Columns

   Here’s another example that removes and replaces some of the columns.

   add_filter('manage_books_posts_columns' , 'book_cpt_columns');
   
   function book_cpt_columns($columns) {
   	unset(
   		$columns['author'],
   		$columns['comments']
   	);
   
   	$new_columns = array(
   		'publisher' => __('Publisher', 'ThemeName'),
   		'book_author' => __('Book Author', 'ThemeName'),
   	);
   
       return array_merge($columns, $new_columns);
   }

   Note that unlike an array data type, the unset PHP function accepts arguments in which the last argument should NOT end with a comma.

   Hide Columns

   Here is an example of how to remove or (hide) columns from Pages / Posts and Custom Post Types without adding any.

   You can also add the name of the custom-post type and filter them out in there too… But if you have 5 custom post types you will need five different filters.

   Note: Replace the text CUSTOMPOSTTYPE below with the name of your post type.

   // Filter pages
   add_filter( 'manage_edit-page_columns', 'my_columns_filter',10, 1 );	
   
   // Filter Posts
   add_filter( 'manage_edit-post_columns', 'my_columns_filter',10, 1 );
   
   // Custom Post Type
   add_filter( 'manage_edit-CUSTOMPOSTTYPE_columns', 'my_columns_filter',10, 1 );
   
   function my_columns_filter( $columns ) {
      unset($columns['author']);
      unset($columns['categories']);
      unset($columns['tags']);
      unset($columns['comments']);
      
      return $columns;
   }

   We need to care while using manage_{$screen->id}_columns hook for media screen because when we used manage_media_columns hook we will receive Too few arguments fatal error in Add New Media File page error.

   <?php
   add_filter( 'manage_media_columns', array( $this, 'filter_media_table_columns' ), 100, 2 );

   This error is coming because in the 'manage_media_columns' filter hook in wp-admin/includes/class-wp-media-list-table.php passes two arguments.
