100% 宽度 +水平和垂直滚动
我的网站宽度为 100%。我的网站经常包含宽表格，有时这些表格比（视口的）100% 更宽。
当发生这种情况时，会出现水平滚动条（这是完全自然的）。但是当我水平滚动时，菜单不遵循最宽表格的宽度。
我尝试了互联网上提供的各种代码示例，但似乎没有一个对我有帮助。下面是我的最新代码，它适用于水平滚动（因为菜单的位置固定）。但是，当页面变得“高”并且需要垂直滚动时，菜单始终可见并固定在其原始视口位置（同样，自然行为）。
有什么方法可以使水平滚动时的行为像现在一样，但垂直滚动时却正常？
如果有人有任何建议，我将不胜感激。

编辑：我设法让它在 IE8 中工作，但 IE7 仍然遇到同样的问题:(
使它在 IE8 中工作的实际上是将 width: 100%; 更改为 min-width: 100% ;，但 IE7 似乎不同意
？

My site has a width of 100%. My site often contains wide tables, and sometimes these tables gets wider than the 100% (of the viewport).
When that happens, a horizontal scrollbar appears (which is fully natural). But when I scroll horizontally, the menu is not following the width of the widest table.
I have tried various code examples available on the Internet, but none seems to help me all the way. Below is my latest code, and it works with the horizontal scrolling (because of the fixed position of the menu). But, when the page gets "high", and vertical scrolling is needed, the menu is always visible and fixed at its original viewport position (again, natural behaviour).
Is there any way to make the behave like it does now when scrolling horizontally, but acting normally when scrolling vertically?
If anyone has any suggestions, I'd be more than grateful.

EDIT: I managed to get it to work in IE8, but IE7 still suffers from the same disease :(
What made it work in IE8 was actually changing width: 100%; into min-width: 100%;, but IE7 doesn't seem to agree.
Anyone?

回答我自己的问题：
经过数小时和数天的尝试，我终于让它在 IE7/IE8 中都能工作，这就是目标。唯一的限制是 IE7，当表格太宽时菜单不会居中。
解决方案是使用 min-width 而不是 width，这样可以让内容增长到视口之外，但如果内容宽度小于视口，则仍然覆盖整个屏幕。
如果将来其他人遇到同样可怕的问题，我将在这里发布代码：
感谢您的支持！
Answer to my own question:
After hours and days of trying, I finally made it work in both IE7/IE8, which was the goal. The only limitation goes for IE7, where the menu is not centered when the table is too wide.
The solution was to use min-width instead of width, which lets the content grow outside of the viewport but still covering the whole screen if the content is less wide than the viewport.
I will post the code here, if anyone else in the future is facing the same terrible issue:
Thanks for the support!
玩完后我能想到的最好办法就是在 body 和 div.myMenu 上设置相同的显式宽度（例如 1800px 或 150em）。然而，要做到这一点，您需要知道哪些页面具有宽表以及它们的大约宽度。我预计会有问题。
The best I could come up with after playing was setting the same explicit width on both the body and the div.myMenu (e.g. 1800px or 150em). To do this, however, you would need to know both which pages had the wide tables and approximately how wide to make them. Problematic I expect.
