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。

Google gives very low priority to text content contained inside a table. I was giving some SEO advice to a local charity. In examining their website it was using tables to layout the site. Looking at each page, no matter what words - or combination of words - from their pages I used in the Google search box the pages would not come up in any of the top search pages. (However, by specifying the site in the search the page was returned.) One page was well copy written by normal standards to produce a good result in a search but still it didn't appear in any of the first pages of search results returned. (Note this text was within a table.) I then spotted a section of text on the pages which was in a div rather than a table. We put a few of the words from that div in the search engine. Result? It came in at No.2 in the search result.

对于为了简单或临时的东西而拼凑在一起的HTML,表很有用。如果你正在构建一个大型网站,你应该使用div和CSS,因为随着时间的推移,随着网站的变化,它将更容易维护。

我曾经处理过一个包含6层嵌套表的网站,这个网站是由一些应用程序生成的,并且生成了无效的HTML,事实上,我花了3个小时的时间来纠正它,因为一个小的改变。

这当然是边缘情况,但是基于表的设计是不可维护的。如果你使用css,你分离了样式,所以在修复HTML时,你不必担心破坏。

同样,用JavaScript试试这个方法。将单个表单元格从一个位置移动到另一个表中的另一个位置。执行起来相当复杂,div/span只需要复制粘贴即可。

“我的老板在乎吗?”

如果我是你的老板。你会在乎的。,)如果你珍视你的生命。

如果你在这方面支持表格角度,找一个有表格的网站,然后给自己买一个屏幕阅读器——关掉屏幕阅读器,关掉你的显示器。

然后尝试一个不错的语义正确的div布局网站。

你会发现其中的不同。

如果表格中的数据是表格而不是为了布局页面,那么表格并不是邪恶的。

Layout should be easy. The fact that there are articles written on how to achieve a dynamic three column layout with header and footer in CSS shows that it is a poor layout system. Of course you can get it to work, but there are literally hundreds of articles online about how to do it. There are pretty much no such articles for a similar layout with tables because it's patently obvious. No matter what you say against tables and in favor of CSS, this one fact undoes it all: a basic three column layout in CSS is often called "The Holy Grail".

如果这不能让你说“WTF”,那么你现在真的需要放下酷爱饮料了。

我喜欢CSS。它提供了惊人的样式选项和一些很酷的定位工具,但作为一个布局引擎,它是有缺陷的。需要某种类型的动态网格定位系统。一个直接的方法来对齐多个轴上的盒子,而不知道他们的大小。我不在乎你叫它<table>或<gridlayout>或其他什么,但这是CSS中缺少的一个基本布局特性。

更大的问题是,由于不承认有缺失的特性,CSS狂热者一直在阻碍CSS的发展。如果CSS能像世界上其他布局引擎一样提供像样的多轴网格定位,我很乐意停止使用表格。(你应该意识到这个问题已经被除了W3C之外的所有人用多种语言解决过很多次了,对吧?没有人否认这样一个功能是有用的。)

叹息。足够的通风。去吧,把头埋进沙子里。
