以下是将垃圾计数修改为999的三种不同方法，例如：

方法#1views_edit-comments 过滤器：

add_filter( \'views_edit-comments\', function( $views ) 
{
    $trash_count = 999; // <-- Adjust this count

    // Override the \'trash\' link:
    $views[\'trash\'] = sprintf(
      "<a href=%s>%s <span class=\'count\'>(<span class=\'trash-count\'>%d</span>)</span></a>",
      esc_url( admin_url( \'edit-comments.php?comment_status=trash\') ),
      __( \'Trash\' ),
      $trash_count
    );
    return $views;
} );

方法2comment_status_links 过滤器：

add_filter( \'comment_status_links\', function( $status_links ) 
{
    $trash_count = 999; // <-- Adjust this count

    // Override the \'trash\' link:
    $status_links[\'trash\'] = sprintf(
      "<a href=%s>%s <span class=\'count\'>(<span class=\'trash-count\'>%d</span>)</span></a>",
      esc_url( admin_url( \'edit-comments.php?comment_status=trash\') ),
      __( \'Trash\' ),
      $trash_count
    );
    return $status_links;
} );

方法3这里我们针对edit-comments.php 屏幕并调整wp_count_comments() 功能：

add_filter( \'load-edit-comments.php\', function() 
{
    add_filter( \'wp_count_comments\', function( $stats, $post_id )
    {
        static $instance = 0;
        if(  2 === $instance++ )
        {
            $stats = wp_count_comments( $stats, $post_id );

            // Set the trash count to 999
            if ( is_object( $stats ) && property_exists( $stats, \'trash\' ) )
                $stats->trash = 999; // <-- Adjust this count
        }
        return $stats;
    }, 10, 2 );
} );

类似地，对于待定和垃圾邮件计数。
