   Suppose you have a ‘book’ custom post type and you want to add the publisher and book author in the edit page but remove the post author.

   add_filter( 'manage_book_posts_columns', 'set_custom_edit_book_columns' );
   add_action( 'manage_book_posts_custom_column' , 'custom_book_column', 10, 2 );
   
   function set_custom_edit_book_columns($columns) {
       unset( $columns['author'] );
       $columns['book_author'] = __( 'Author', 'your_text_domain' );
       $columns['publisher'] = __( 'Publisher', 'your_text_domain' );
   
       return $columns;
   }
   
   function custom_book_column( $column, $post_id ) {
       switch ( $column ) {
   
           case 'book_author' :
               $terms = get_the_term_list( $post_id , 'book_author' , '' , ',' , '' );
               if ( is_string( $terms ) )
                   echo $terms;
               else
                   _e( 'Unable to get author(s)', 'your_text_domain' );
               break;
   
           case 'publisher' :
               echo get_post_meta( $post_id , 'publisher' , true ); 
               break;
       }
   }
