对jsp网页布局

lsmsilence 2009-12-02 09:53:50

我有一段JSP写的网页，里面用了大量的标签，但是我现在想在整个网页外加一个大表格，是整个网页不占满整个屏幕，而是按照宽度为1003像素固定显示，但是用表格不行，请问应该怎么弄？
代码如下，我也不知道用没用框架，好像没用，但是左边的导航栏始终控制不了宽度

不需要在外边加一个table。想必你也在研究Dspace吧。
方法是把/webapps/jspui/下的styles.css.jsp文件打开，
BODY{...}中添加width:1003px;(我更喜欢960px)
对照修改： margin:auto;
注释掉这两行：/* margin-left:0px;
margin-right:0px;*/
就可以了。
另外，请问您在哪个单位呀？
