好吧，这里是下一篇关于带有固定页眉和页脚的无聊滚动表的帖子。这个话题来自HTML的刚性结构。源问题是显示非常大的表格溢出屏幕宽度作为高度。我的愿望也是将标题固定在表格的顶部，因此将其副本固定在表格的底部。
经过大量谷歌搜索和测试大量有保证的代码后，我发现了下一个深层嵌套问题: - 当 tbody 单独滚动时，页眉和页脚不保持表体的单元格间距 - tbody 行覆盖标题 - tbody 的垂直滚动很难与整个表格(包括页眉和页脚)的水平滚动相结合。
我开始写一些 hack 来克服它，但这也取决于使用的浏览器。

该解决方案基于创建三个表:标题表、数据表、页脚表(标题表的克隆)，包含在水平滚动的 DIV 中。 header-table和data-table构建完成后，将data-table自动生成的cell-with复制到header-table对应的cell中。 一些缺点是垂直滚动条隐藏在表格的右侧，但您可以使用鼠标滚轮垂直滚动或通过水平滚动到最右侧显示该条。 可能这里有人展示了一些基于 CSS 的更好的解决方案，这真的很好，但如果 W3C 小组将定义的正常滚动行为添加到下一个 HTML 版本中，情况可能会更好。
嗯，这篇文章是作为 html 可滚动表格的功能示例编写的，固定的页眉和页脚始终可见。不少，也不少，漂亮的装饰也没有。基本任务是尽可能简单地编写它。由于此表旨在成为更复杂的 html 页面的一部分，包含公式和其他表，因此排除了全局 CSS。在过去 30 年 W3C 对 HTML 特性进行了大量开发之后，我预计会是这样的:
<table style="overflow:scroll; overflow-y:hidden; display:@in_parent_element_only">
<thead style="'header cells corresponding with table cells'">
<row><!--single row header --></row></thead>
<tbody style="overflow:scroll; overflow-x:hidden; 'full_view_table'">
<row><!--lot of rows --></row></tbody>
<tfoot ><row><!--copy of header --></row></tfoot>
</table>
不幸的是，这应该是一种过于简单的方法 - 实际上我测试了很多样式组合，但是 THEAD 和 TBODY 单元格不相关(为什么？)，或者 THEAD、TBODY、TFOOT 行重叠或替换每个其他，反之亦然。
我知道，通过繁重的计算、定位和样式可以得到非常好的结果，但我坚持简单性和功能性，更喜欢信息而不是装饰。
如果有人知道内联 style=".." 的什么组合可以保证良好的结果，而不管浏览器类型如何，请尝试在这里写一段注释良好的代码。不仅是为了我，也是为了社区，就像我在这里展示的原始方式一样。
最佳答案
我对这段旧代码的研究很急躁，所以我做了一个新的 ;-)
