我们今天遇到了同样的问题。一个漂亮的解决方案也许并不明显，但也并非不可能。

下面是我们用来只显示与每个作者相关的计数的代码。有权编辑其他用户帖子的用户仍将看到完整计数。

add_filter(\'wp_count_posts\', \'wpse149143_wp_count_posts\', 10, 3);


/**
 * Modify returned post counts by status for the current post type.
 *  Only retrieve counts of own items for users without rights to \'edit_others_posts\'
 *
 * @since   26 June 2014
 * @version 26 June 2014
 * @author  W. van Dam
 *
 * @notes   Based on wp_count_posts (wp-includes/posts.php)
 *
 * @param object $counts An object containing the current post_type\'s post
 *                       counts by status.
 * @param string $type   Post type.
 * @param string $perm   The permission to determine if the posts are \'readable\'
 *                       by the current user.
 * 
 * @return object Number of posts for each status
 */
function wpse149143_wp_count_posts( $counts, $type, $perm ) {
    global $wpdb;

    // We only want to modify the counts shown in admin and depending on $perm being \'readable\' 
    if ( ! is_admin() || \'readable\' !== $perm ) {
        return $counts;
    }

    // Only modify the counts if the user is not allowed to edit the posts of others
    $post_type_object = get_post_type_object($type);
    if (current_user_can( $post_type_object->cap->edit_others_posts ) ) {
        return $counts;
    }

    $query = "SELECT post_status, COUNT( * ) AS num_posts FROM {$wpdb->posts} WHERE post_type = %s AND (post_author = %d) GROUP BY post_status";
    $results = (array) $wpdb->get_results( $wpdb->prepare( $query, $type, get_current_user_id() ), ARRAY_A );
    $counts = array_fill_keys( get_post_stati(), 0 );

    foreach ( $results as $row ) {
        $counts[ $row[\'post_status\'] ] = $row[\'num_posts\'];
    }

    return (object) $counts;
}

我认为最简单的方法就是用CSS隐藏它们，您可以尝试以下方法：

add_action( \'admin_head\', \'wpse145565_hide_post_count\' );

function wpse145565_hide_post_count() {
    $css  = \'<style>\';
    $css .= \'.subsubsub a .count { display: none; }\';
    $css .= \'</style>\';

    echo $css;
}

在WordPress 5.7中，上述代码工作不正常。例如，在“我的”的情况下，它不起作用。所以我修改了上面的代码。

function custom_editor_counts($views){
    
    $iCurrentUserID = get_current_user_id();

    global $wpdb;

    foreach ($views as $index => $view){
        
        if (in_array($index, array(\'all\')))
            continue;
        
        // There is no mine for post_status. However, it can be derived using the summation of pending and publish count.
        if(strcmp(\'mine\',$index)== 0){
            
            $viewValue = $wpdb->get_var("SELECT COUNT(*) FROM $wpdb->posts WHERE post_type=\'post\' AND post_author = $iCurrentUserID and (post_status=\'pending\' || post_status=\'publish\' || post_status=\'draft\')");
            
        }else{
            
            $viewValue = $wpdb->get_var("SELECT COUNT(*) FROM $wpdb->posts WHERE post_type=\'post\' AND post_author = \'" . $iCurrentUserID . "\' AND post_status=\'$index\'");
            
        }
        
        // Replace the existing value from the update one.
        $views[$index] = preg_replace(\'/\\(.+\\)/U\', \'(\' . $viewValue . \')\', $views[$index]);
        
    }


    unset($views[\'all\']);   
    return $views;

}

# It is for non admin users. For example contributors, etc.
if (!current_user_can(\'manage_options\')){
    add_filter("views_edit-post", \'custom_editor_counts\', 10, 1);
}
