本文在html中利用js＋table实现分页。主要思想是先对table中的所有数据隐藏，然后通过当前页面(currPageNum)来计算当前页要显示的行，并显示出来，首页、下一页、上一页、尾页都依此来实现。
可以直接运行。
一、html页面
1. 在页面中直接向table写好数据，定义table的id；
2. 在页面中加入首页、上一页、下一页、尾页，当前页、总页数等标签；
3. 在页面中的javascript部分声明会用到的变量，并写好加载函数，window.onload=function(){...}。
二、js部分
1. 在js文件中依次实现首页、上一页、下一页、尾页等功能；
2. 控制首页等功能的显示与不显示。
以下是代码部分 ，欢迎批评与指正。
js文件为pagination.js
