table :创建一个表格；align="center" 表格对齐格式为置中；cellpadding ="1" 表格中单元格在原有基础上沿四边各加上1个点子宽度。cellspacing ="0" 表格中单元格之间的空白量（也可理解为左侧缩进）
<table align="center"> <tr> <td></td> </tr> </table> 和 <table> <tr> <td align="center"></td> </tr> </table> 这两个是不一样的，前者是表格居中，后者是单元格中的内容居中。

那是因为 align="center"并不是所有浏览器都能用，IE8本来就不遵守W3C标准，只用它自己的标准。你可以在body里加 margin:auto; 或者在table外面加个div 给div加margin:0 auto 样式就好了。你以后会知道很多标准就是被IE搞坏的。。。需要换很多浏览器测试 ...
text-align:center;是让文字居中，只对文字有效果。你要让table居中，可以试试margin：0px auto;并且是要加在table上。如果你要加给div，你要给div定义宽和高那么才起作用。
