为什么不在HTML中使用表格布局呢?

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。

I have found that even with the best planning divs come up short in several respects. For instance. there is no way with divs to have a bottom bar that always sits at the bottom of the browser, even when the rest of the content does not go to the bottom of the browser. Also, you cannot elegantly do anything better than three columns, and you cannot have columns that grow and shrink according the the width of their content. In the end, we try to use divs first. However, we will not limit our html designs based on some religious content vs layout ideal.

在维护内容的同时进行网站维护和设计检修(这一直都在发生，尤其是在电子商务中):

内容和设计通过表格混合在一起=更新内容和设计。

内容与设计分离=更新设计和少量内容。

如果我有自己的方式，我会将内容保存在PHP中，生成XML，转换为XSLT中的标记，并使用CSS和Javascript进行交互设计。对于Java方面的东西，JSP到JSTL来生成标记。

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。

看这个重复的问题。

你忘记的一项是可访问性。例如，如果你需要使用屏幕阅读器，基于表格的布局就不能很好地转换。如果您使用政府，则可能需要支持可访问的浏览器，如屏幕阅读器。

我也认为你低估了你在问题中提到的一些事情的影响。例如，如果您既是设计人员又是程序员，您可能没有充分了解它如何将表示和内容分开。但一旦你进入一个商店，他们是两个不同的角色，优势就开始变得清晰起来。

如果你知道你在做什么并且有好的工具，CSS在布局方面确实比表格有显著的优势。虽然每一件物品本身都不能证明放弃餐桌是合理的，但总的来说还是值得的。

看起来你只是习惯了桌子，仅此而已。将布局放在表格中会限制你的布局。用CSS你可以移动位，看看http://csszengarden.com/ 不，布局通常不需要很多嵌套的div。

没有表格的布局和适当的语义HTML更干净，因此更容易阅读。为什么不理解CSS的人要尝试阅读它呢?如果有人认为自己是web开发人员，那么对CSS的良好掌握是必须的。

SEO的好处来自于将最重要的内容放在页面上方的能力拥有更好的内容与标记比率。

我想使用表格元素进行布局确实与表格数据没有什么关系。那又怎样?我的老板在乎吗?我的用户关心吗?
