只在WP主评论加上楼层号的方法via:http://zww.me/archives/25161/

//主评论计数器初始化 begin - by zwwooooo
	global $commentcount;
	if(!$commentcount) { //初始化楼层计数器
		$page = get_query_var('cpage')-1;
		$cpp=get_option('comments_per_page');//获取每页评论数
		$commentcount = $cpp * $page;
	}
//主评论计数器初始化 end - by zwwooooo

		<div class="floor"><!-- 主评论楼层号 by zwwooooo -->
			<?php if(!$parent_id = $comment->comment_parent) {printf('#%1$s', ++$commentcount);} ?><!-- 当前页每个主评论自动+1 -->
		</div>

ol.commentlist li div.floor{position:absolute;top:0;right:0;}
