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。

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.

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。

我尽量避免使用TABLEs,但是当我们设计复杂的表单,混合了多种控件类型和不同的标题位置,并对分组进行了非常严格的控制时,使用DIVs是不可靠的,甚至几乎是不可能的。

现在,我不会说这些表单不能重新设计以更好地适应基于DIV的布局,但是对于其中的一些表单,我们的客户坚决不改变以前版本(用经典ASP编写的)的现有布局,因为它与用户熟悉的纸质表单相似。

因为表单的表示是动态的(其中某些部分的显示是基于案例的状态或用户的权限),所以我们使用一组堆叠的div,每个div包含一个由逻辑分组的表单元素组成的TABLE。TABLE的每一列都被分类,这样CSS就可以控制它们。这样,我们就可以关闭表单的不同部分,而不会出现在div中不是表来换行的问题。

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

The issue of strictly separating presentation and content strikes me as roughly analogous to separating header files from implementation files in C++. It makes sense, but it can also be a pain. Witness Java and C# where classes are defined in a single source file. The authors of the newer languages noticed something that was causing programmers headaches and they got rid of it. That seems to be the gist of this discussion. One side is saying CSS is too difficult, the other side is saying one must become a CSS master.

对于简单的布局问题,为什么不改变表示必须完全独立的规则呢?一个新的标签(或者一些div标签的扩展)可以让我们直接在HTML中控制显示?毕竟,我们不是已经将表示泄露到HTML中了吗?看看h1, h2, h6。我们都知道这些控制表示。

阅读代码(HTML就是代码)的能力非常重要。专家们往往忽略了使编程环境尽可能为大众所接受的重要性。认为只有专业程序员才重要是非常短视的。
