【问题描述】：
好吧，这是关于带有固定页眉和页脚的无聊滚动表的下一篇文章。这个话题来自于 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。我还希望将表头固定在表格顶部，并将其副本固定在表格底部。
经过深入的谷歌搜索和大量有保证的代码测试后，我发现了下一个深层嵌套问题： - 单独滚动 tbody 时，页眉和页脚不保持表格主体的单元格间距 - tbody 行覆盖标题 - tbody 的垂直滚动几乎不能与整个表格（包括页眉和页脚）的水平滚动结合。
我开始写一些技巧来克服它，但这也取决于使用的浏览器。

解决方案基于创建三个表：header-table、data-table、footer-table（header-table 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 的自动生成的 cell-with 复制到 header-table 的相应单元格中。 一些缺点是垂直滚动条隐藏在表格的右侧，但是您可以使用鼠标滚轮垂直滚动或通过水平滚动到完全右侧来显示条。 可能有人在这里展示了一些基于 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。不多也不少，也不是漂亮的装饰。基本任务是尽可能简单地编写它。由于该表旨在成为更复杂的 html 页面的一部分，其中包含公式和其他表，因此不包括全局 CSS。在 W3C 在过去 30 年中大力开发 HTML 功能之后，我想到了类似的东西：
<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 THEAD 和 TBODY 单元格不相关（为什么？），或者 THEAD、TBODY、TFOOT 行重叠或取代每个其他，反之亦然。
我知道，一个非常好的结果可以通过繁重的计算、定位和样式来寻找，但我坚持简单和功能，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无论浏览器类型如何都能获得良好的结果，请尝试在此处编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我的原始方式一样。
