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。


当前回答

根据过去的经验,我必须选择DIV。即使在OOP中,主要目的也是减少对象之间的耦合,因此这个概念可以应用于DIVS和表。表用于保存数据,而不是围绕页面排列数据。DIV是专门设计用于在页面周围排列项目的,因此设计应该使用DIV,表应该用于存储数据。

此外,编辑由表格组成的网站是非常困难的(在我看来)

其他回答

数据:使用表格。布局:使用样式。使用非常精简的浏览器(即没有样式,只有普通标记的Links 2或Lynx)可以最快地呈现表。

根据508法规(对于视障屏幕阅读器),表格应该只用于保存数据,而不是用于布局,因为它会导致屏幕阅读器崩溃。至少别人是这么告诉我的。

如果您为每个div分配名称,您也可以使用CSS将它们一起蒙皮。只是让他们坐成你想要的样子有点麻烦。

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。

我没有对DIVs有利的论据。

我会说:如果事实属实,那就接受吧。

值得注意的是,要找到一种好的DIV+CSS方法来在两列或三列中呈现内容,并且在所有浏览器上都是一致的,并且看起来仍然是我想要的方式,即使不是不可能,也是很困难的。

在我的大多数布局中,这让平衡感向表格倾斜了一点,尽管我对使用它们感到内疚(不知道为什么,人们只是说它不好,所以我试着听他们的),最后,务实的观点是,对我来说,使用表格更容易、更快。我不是按小时计酬的,所以桌子对我来说比较便宜。

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?

谷歌和其他自动化系统确实关心这些问题,而且它们在许多情况下同样重要。语义代码对于非智能系统来说更容易解析和处理。
