篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了HTML中table带滚动条而标题栏不移动的做法相关的知识，希望对你有一定的参考价值。
看到有人说可以用一个TABLE里面套两个TABLE来做,其中一个只作为标题栏,另一个嵌套在有滚动条的DIV里面.但是这样一来,标题栏和数据部分因为宽度不一样,对不上了.而我做的这个TABLE,一行有多少列数据是不固定的,而且每列显示什么项目也不固定,每个<TH>或者<TD>的宽度是无法固定的.不知道哪位大仙能帮忙想给别的办法呢?100分,全都送上,谢了.

具体思路这个是一个大table，然后表头与结果域各一个table，
表头的标题是N个，那么就需要分N＋1个td，前面N个TD的width总和为100％，最后1个为了给滚动条位置，不然不好与下面table对齐。
下面的结果体table需要包含在div中，设置td的长度与上面td长度要保持一致，这样就可以了。 参考技术B 在标题的tr中添加如下样式
style="position: relative; top: expression(this.offsetParent.scrollTop);"
