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。

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。

其他回答

我认为没有人会在意一个网站是如何设计/实现的,当它运行得很好并且运行得很快的时候。

我在HTML标记中同时使用“table”和“div”/“span”标记。

让我给你一些我为什么选择跳水的理由:

for a table you have to write at least 3 tags (table, tr, td, thead, tbody), for a nice design, sometimes you have a lot of nested tables I like to have components on the page. I don't know how to explain exactly but will try. Suppose you need a logo and this have to be placed, just a small piece of it, over the next page content. Using tables you have to cut 2 images and put this into 2 different TDs. Using DIVs you can have a simple CSS to arange it as you want. Which solution do you like best? when more then 3 nested tables for doing something I am thinking to redesign it using DIVs

但是我仍然在使用表格:

表格数据 扩展自我的内容 快速解决方案(原型),因为DIVs盒子模型在每个浏览器上是不同的,因为许多生成器使用表格等

我想补充的是,基于div的布局更容易维护、发展和重构。只是在CSS中做了一些改变来重新排序元素,这就完成了。根据我的经验,重新设计使用表的布局是一场噩梦(如果有嵌套的表,则会更糟)。

从语义的角度来看,代码也有意义。

当您需要确保元素在布局中保持特定的物理关系时,请使用表格。对于数据,表格通常是最适合使用的布局元素,因为您不希望列以超出预期的方式包装,从而混淆了关联。

也有人可能会说,必须保持特定关系的非数据元素也应该呈现在表中。

灵活的css布局非常适合于移动设备、大屏幕、打印和其他显示类型的内容,但有时,内容必须以非常特定的方式显示,如果这要求屏幕阅读器无法轻松访问它,那么它可能是非常合理的。

不幸的是,CSS Zen Garden不能再作为一个好的HTML/CSS设计的例子。实际上,他们最近的所有设计都使用图形作为部分标题。这些图形文件是在CSS中指定的。

因此,一个网站的目的是展示将设计排除在内容之外的优势,现在却经常犯将内容纳入设计的不可言说的罪。(如果HTML文件中的节标题要更改,则显示的节标题不会更改)。

这只能说明,即使是那些提倡严格的DIV和CSS宗教的人,也不能遵循他们自己的规则。你可以用它来指导你如何严格遵守它们。

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.
