大家经常遇到再ie中打印表格时需要隐藏一些不需要打印的对象，比如说按钮，输入框，或者希望莫个表格显示的时候表格线是由颜色的，而打印的时候只需要有粗细之分，其实在css中可以设定在打印或者显示的不同样式，最近作了一个应用（实属逼上梁山），可以得到以上效果，下面是我的样式表。。。。
<style type="text/css" media=print  主要是media选项对照下面的那一个style一起看
.noprint{visibility:hidden}
        span.double {BORDER-BOTTOM-STYLE: double; BORDER-LEFT-STYLE: double;
