我正在使用一个数据表我正在使用传统的表格标记,但我想要的是我的表从页面的某个地方开始,我希望我的表格标题在它开始的地方固定,并且表格主体应该通过删除其余页面来滚动高度

我知道我们可以从flex-Box响应表中获取它,但我的限制是我必须使用传统的表标记,所以如果告诉我是否有任何其他方式比flexBox响应表
谢谢
解决方法
可滚动表固定标题技巧不能用于自动列宽.这是因为它们更改了tbody元素的display属性,从而创建了一个具有不同列宽的新(匿名)表.
我能想到的最好的解决方案是创建表的副本(以便两者具有相同的内容,因此具有相同的列宽)并独立操作它们.
在下面的示例中,我使用jQuery创建表和可见性的副本：折叠以隐藏表头和正文：
$(function() {
$("#button-1").one("click",function() {
$(".datatable").clone().insertAfter(".datatable");
$(".datatable").eq(0).addClass("tablehead");
$(".datatable").eq(1).addClass("tablebody");
});
});
/* full height */
html { height: 100%; }
body { height: 100%; margin: 0; padding: 0; font: medium monospace; }
/* make last item scrollable and occupy available height */
#wrapper { height: 100%; display: flex; flex-direction: column; overflow-y: hidden; }
#wrapper > :last-child { display: block; flex: 1; overflow-y: auto; }
/* make thead and tbody collapse when JavaScript adds the classes */
.datatable.tablehead tbody { visibility: collapse; }
.datatable.tablebody thead { visibility: collapse; }
/* beautify */
.datatable { border-collapse: collapse; }
.datatable th { border: 1px solid; background-color: #CCC; }
.datatable td { border: 1px solid; padding: 5px; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<!--
Notes:
1) Using a wrapper div instead of body because third party scripts
often append elements to body element breaking our flex model
2) Width of second column is determined by thead > 1st row > 2nd column
while width of third column is determined by tbody > 1st row > 3rd column
3) If JavaScript fails the result is still usable

请注意,在所有浏览器中都无法正确实现可见性：崩溃.替代解决方案是将两个表包装在div中：固定高度div用于头表,可滚动div用于body表.但是你需要设置标题的高度.
