要自定义列，基本上需要manage_edit-$post-type_columns 筛选器和“manage\\u$post-type\\u posts\\u custom\\u column”操作挂钩。前者告诉WordPress您要显示的列的名称，后者提供HTML以回应每个特定列。。。尤其是WordPress尚未定义的自定义列。

以下示例摘自Custom columns for custom post types by Justin Tadlock 并将自定义的“持续时间”和“流派”列添加到“电影”帖子类型中。

add_filter( \'manage_edit-movie_columns\', \'my_edit_movie_columns\' ) ;

function my_edit_movie_columns( $columns ) {

    $columns = array(
        \'cb\' => \'<input type="checkbox" />\',
        \'title\' => __( \'Movie\' ),
        \'duration\' => __( \'Duration\' ),
        \'genre\' => __( \'Genre\' ),
        \'date\' => __( \'Date\' )
    );

    return $columns;
}

add_action( \'manage_movie_posts_custom_column\', \'my_manage_movie_columns\', 10, 2 );

function my_manage_movie_columns( $column, $post_id ) {
    global $post;

    switch( $column ) {

        /* If displaying the \'duration\' column. */
        case \'duration\' :

            /* Get the post meta. */
            $duration = get_post_meta( $post_id, \'duration\', true );

            /* If no duration is found, output a default message. */
            if ( empty( $duration ) )
                echo __( \'Unknown\' );

            /* If there is a duration, append \'minutes\' to the text string. */

                    );
                }
