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。

我不得不用这两种方式来做网站,再加上第三种,可怕的“混合”布局,包括表格、div和样式:div /CSS轻松胜出。

为了匹配一个表格单元格的代码权重,您必须立即嵌套三个深度的div。这种效果会随着嵌套表的增加而扩大。

我也更喜欢做一个布局变化,而不是一个变化,在我的网站的每一页。

我可以完全控制divs/css的各个方面。表格以一种可怕的方式把它搞得一团糟,尤其是在IE浏览器中,我从来没有选择不支持这个浏览器。

我维护或重新设计一个div /css网站的时间只是表格的一小部分。

最后,我可以用CSS和几乎任何脚本语言创新多种可切换的布局。这对我来说是不可能的。

在你做决定的时候,祝你的投资回报率好运。

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。

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.

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。

内容和布局之间的分离也使它更容易为您的网站生成打印机友好的布局或不同的皮肤(样式),而不必创建不同的html文件。有些浏览器(如Firefox)甚至支持从视图菜单中选择样式表。

而且我确实认为保持无表格布局更容易。你不需要担心行span, colspan等等。您只需创建一些容器div并将内容放置在需要的位置。也就是说,我认为它也更有可读性(<div id="sidebar"> vs <tr><td>…</td><td>…<td>sidebar</td></tr>)。

这只是一个你必须学会的小“技巧”(一旦你掌握了这个技巧,我认为它会更容易,更有意义)。

我曾经了解到,一个表是立即加载的,换句话说,当连接很慢的时候,表所在的空间保持空白,直到整个表被加载,另一方面,一个div加载从上到下的速度与数据到达的速度一样快,不管它是否已经完成。
