在HTML中，表格不应该用于布局，这似乎是普遍的观点。
Why?
我从来没有(老实说，很少)看到过支持这一点的有力论据。通常的答案是:
It's good to separate content from layoutBut this is a fallacious argument; Cliche Thinking. I guess it's true that using the table element for layout has little to do with tabular data. So what? Does my boss care? Do my users care?Perhaps me or my fellow developers who have to maintain a web page care... Is a table less maintainable? I think using a table is easier than using divs and CSS.By the way... why is using a div or a span good separation of content from layout and a table not? Getting a good layout with only divs often requires a lot of nested divs.
Readability of the codeI think it's the other way around. Most people understand HTML, few understand CSS.
It's better for SEO not to use tablesWhy? Can anybody show some evidence that it is? Or a statement from Google that tables are discouraged from an SEO perspective?
Tables are slower.An extra tbody element has to be inserted. This is peanuts for modern web browsers. Show me some benchmarks where the use of a table significantly slows down a page.
A layout overhaul is easier without tables, see css Zen Garden.Most web sites that need an upgrade need new content (HTML) as well. Scenarios where a new version of a web site only needs a new CSS file are not very likely. Zen Garden is a nice web site, but a bit theoretical. Not to mention its misuse of CSS.
我对使用divs + CSS而不是表的良好参数非常感兴趣。
这并不一定是一场战争。和谐是可能的。
使用一个表的整体布局和div在其中。
<table>
<tr><td colspan="3"><div>Top content</div></td></tr>
<tr>
<td><div>Left navigation</div></td>
<td><div>Main content</div></td>
<td><div>Right navigation</div></td>
</tr>
<tr><td colspan="3"><div>Bottom content</div></td></tr>
</table>
看，没有嵌套表。
我读过很多关于如何用divs实现这一点的文章，但从来没有发现任何事情，每次都没有问题。
一旦你有了整体结构，Divs是很棒的，但坦率地说，流体页眉/页脚和三个流体列是Divs的一大痛苦。Divs不是为流动性而设计的，所以为什么要使用它们呢?
注意，这种方法将在链接文本中提供100%的CSS遵从性
一张桌子来布置也不错。但大多数情况下，仅靠一张表是无法得到所需的布局的。很快你就有了2到3个嵌套表。这变得非常麻烦。
It IS a LOT harder to read. That's not up to opinion. There's just more nested tags with no identifying marks on them.
Separating content from presentation is a good thing because it allows you to focus on what you're doing. Mixing the two leads to bloated pages that are hard to read.
CSS for styles allows your browser to cache the files and subsequent requests are much faster. This is HUGE.
Tables lock you into a design. Sure, not everyone needs the flexibility of CSS Zen Garden, but I've never worked on a site where I didn't need to change the design a little bit here and there. It's much easier with CSS.
Tables are hard to style. You don't have very much flexibility with them (i.e. you still need to add HTML attributes to fully control a table's styles)
我大概有4年没有用表格来处理非表格数据了。我没有回头。
我真的很想建议你阅读Andy Budd的《CSS Mastery》。棒极了。

使用DIV，您可以轻松地进行切换。例如，你可以这样做:
Menu | Content
Content | Menu
Menu
----
Content
在CSS中更改它很容易，而在HTML中则不然。你也可以提供几种风格(右手，左手，专为小屏幕)。
在CSS中，您还可以将菜单隐藏在用于打印的特殊样式表中。
另一个好处是，你的内容在代码中总是按照相同的顺序(菜单在前，内容在后)，即使在视觉上它是以其他方式呈现的。
