先删除默认的分类 标签 日期 然后自己添加 要不然 名字可以改 但是内容替换不掉 如果只删除需要更改的默认列 填加的列表是在最后一个 位置暂时不知道怎么调整 所以用的笨方法

function add_views_column($columns)
{ 
    unset($columns['categories']);////删除默认列
    unset($columns['tags']);//删除默认列
    unset($columns['date']);//删除默认列
    $columns['cb'] = '<input type="checkbox" />';
    $columns['title'] = _x( 'Title', 'column name' );
    $columns['post_cat'] = 'カテゴリー';
    $columns['date'] = _x('Date', 'column name');
    return $columns;
}
add_filter('manage_posts_columns', 'add_views_column');
function views_column_content($columns, $post_id)
{
    global $wpdb;
    switch ($columns) {
       
        case 'post_cat':
            $category = get_the_category();
            $category_name = get_category($category)->name;
            $cat_parent_id = $category[0]->category_parent;
            $cat_parents_id = get_category($cat_parent_id)->category_parent;
            $cat_parents_name = get_category($cat_parents_id)->name;
            if (!empty($cat_parents_name)) {
                echo get_category($cat_parent_id)->name;
            } else if (empty($cat_parents_name)) {
                echo $category[0]->name;
            }

            break;
            
        


    }


}
add_action('manage_posts_custom_column', 'views_column_content', 10, 2);

删除默认列用unset($column[‘列名’])，默认的列名如下。

1. cb – 复选框
2. title – 文章标题
3. author – 文章作者
4. categories – 文章的分类
5. tags – 文章的标签
6. comments – 文章的评论
7. date – 文章发布的日期
8. subtitle – 文章副标题
9. 其他自定义

 $new_columns['thumbnail'] = _x('Thumbnail');


case 'thumbnail':
            if (has_post_thumbnail()){
                $array_image_url = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), array(75,60)); ?>
            <img width="75" height="60" src="<?php echo $array_image_url[0];?>">
            <?php }else{
                echo 'None';
            }
            break;
        default:
            break;
