   To add “Template” column into page list:

   add_filter( 'manage_pages_columns', 'page_column_views' );
   add_action( 'manage_pages_custom_column', 'page_custom_column_views', 5, 2 );
   function page_column_views( $defaults )
   {
   	$defaults['page-layout'] = __('Template', 'textdomain');
   	return $defaults;
   }
   function page_custom_column_views( $column_name, $id )
   {
   	if ( $column_name === 'page-layout' ) {
   		$set_template = get_post_meta( get_the_ID(), '_wp_page_template', true );
   		if ( $set_template == 'default' ) {
   			echo __('Default Template', 'textdomain');
   		}
   		$templates = get_page_templates();
   		ksort( $templates );
   		foreach ( array_keys( $templates ) as $template ) :
   			if ( $set_template == $templates[$template] ) echo $template;
   		endforeach;
   	}
   }

   To add to other post types (not post, page or attachment…):

   The hooks to create custom columns and their associated data for a custom post type are manage_{$post_type}_posts_columns and manage_{$post_type}_posts_custom_column respectively, where {$post_type} is the name of the custom post type.

   // Add the custom columns to the book post type:
   add_filter( 'manage_book_posts_columns', 'set_custom_edit_book_columns' );
   function set_custom_edit_book_columns($columns) {
       unset( $columns['author'] );
       $columns['book_author'] = __( 'Author', 'textdomain' );
       $columns['publisher'] = __( 'Publisher', 'textdomain' );
   
       return $columns;
   }
   
   // Add the data to the custom columns for the book post type:
   add_action( 'manage_book_posts_custom_column' , 'custom_book_column', 10, 2 );
   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)', 'textdomain' );
               break;
   
           case 'publisher' :
               echo get_post_meta( $post_id , 'publisher' , true ); 
               break;
   
       }
   }

   Example migrated from Codex:

   Once you have added your column (for this example, thumbnail), the featured image can be displayed for that page in the new thumbnail column.

   function custom_page_column_content( $column_name, $post_id ) {
   	if ( $column_name == 'thumbnail' ) {
   		$post_thumbnail_id = get_post_thumbnail_id( $post_id );
   		if ( $post_thumbnail_id ) {
   			$post_thumbnail_img = wp_get_attachment_image_src( $post_thumbnail_id, 'thumbnail' );
   			echo '<img src="' . $post_thumbnail_img[0] . '" />';
   		}
   	}
   }
   
   add_action( 'manage_pages_custom_column', 'custom_page_column_content', 10, 2 );
