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。
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
我很抱歉我的英语不好,但还有一个原因:
我在一些政府机构工作,不使用TABLE的首要原因是残疾人。他们使用机器“翻译”网页。
问题是这个“翻译机器”不能阅读网站,如果它是由TABLE。为什么?因为TABLE是用于数据的。
事实上,如果你使用TABLES,你必须为每个cell指定一些信息,让残疾人知道他们在TABLE中的位置。想象一下,你有一个大表格,必须放大才能看到屏幕上的一个单元格:你必须知道你在哪一行/col。
因此,使用DIV,并且禁用可以简单地阅读文本,并且不会得到一些关于行/cols的奇怪信息,当它们不需要在那里时。
我也更喜欢TABLE来制作快速简单的模板,但我现在习惯了CSS…它很强大,但你真的必须知道你在做什么……:)
一般来说,表并不比CSS更容易或更易于维护。然而,在一些特定的布局问题中,表确实是最简单和最灵活的解决方案。
在表示标记和CSS支持相同类型的设计的情况下,CSS显然是更可取的,没有人会认为字体标记比在CSS中指定排版更好,因为CSS提供了与字体标记相同的功能,但以一种更干净的方式。
The issue with tables, however, is basically that the table-layout model in CSS is not supported in Microsoft Internet Explorer. Tables and CSS are therefore not equivalent in power. The missing part is the grid-like behavior of tables, where the edges of cells align both vertically and horizontally, while cells still expand to contain their content. This behavior is not easy to achieve in pure CSS without hardcoding some dimensions, which makes the design rigid and brittle (as long as we have to support Internet Explorer - in other browsers this is easliy achieved by using display:table-cell).
因此,这并不是一个表或CSS更可取的问题,而是一个认识到使用表可以使布局更灵活的具体情况的问题。
不使用表的最重要原因是可访问性。Web内容可访问性指南http://www.w3.org/TR/WCAG10/建议不要使用表格进行布局。如果您担心可访问性(在某些情况下,您可能有法律义务这样做),即使表更简单,也应该使用CSS。请注意,您总是可以用CSS创建与表相同的布局,这可能只是需要更多的工作。
