使用表格布局的工具可能会因为创建布局所需的大量代码而变得异常沉重。SAP的Netweaver Portal默认使用TABLE来布局页面。

在我目前的工作中，生产SAP门户有一个主页，它的HTML超过60K，有7个表那么深，在页面中有3次。再加上Javascript，误用了16个iframe，其中有类似的表格问题，CSS过重等，页面重量超过5MB。

花点时间降低页面重量，这样你就可以利用带宽与用户进行互动，这是值得的。

我相信这是一个与普遍问题有关的问题。HTML诞生时，没有人能预见到它的广泛应用。另一项在自身成功的重压下几乎崩溃的技术。当HTML页面用vi在绿色文本终端上编写时，向页面访问者显示数据所需要的只是一个TABLE，而且大多数数据都是以表格形式显示的。

我们都知道事物是如何进化的。相对来说，table最近已经过时了，但是有很多理由更喜欢基于div和CSS的布局(可访问性不是最后一个)。当然我不能写一个CSS来拯救我的生命:-)，我认为图形设计专家应该总是在手边。

也就是说……即使在现代网站中，也有许多数据应该在表格中显示。

I still don't quite understand how divs / CSS make it easier to change a page design when you consider the amount of testing to ensure the changes work on all browsers, especially with all the hacks and so on. Its a hugely frustrating and tedious process which wastes large amounts of time and money. Thankfully the 508 legislation only applies to the USA (land of the free - yeah right) and so being as I am based in the UK, I can develop web sites in whatever style I choose. Contrary to popular (US) belief, legislation made in Washington doesn't apply to the rest of the world - thank goodness for that. It must have been a good day in the world of web design the day the legislation came into force. I think I'm becoming increasingly cynical as I get older with 25 years in the IT industry but I feel sure this kind of legislation is just to protect jobs. In reality anyone can knock together a reasonable web page with a couple of tables. It takes a lot more effort and knowledge to do this with DIVs / CSS. In my experience it can take hours and hours Googling to find solutions to quite simple problems and reading incomprehensible articles in forums full of idealistic zealots all argueing about the 'right' way to do things. You can't just dip your toe in the water and get things to work properly in every case. It also seems to me that the lack of a definitive guide to using DIVS / CSS "out of the box", that applies to all situations, working on browsers, and written using 'normal' language with no geek speak, also smells of a bit of protectionism. I'm an application developer and I would say it takes almost twice as long to figure out layout problems and test against all browsers than it does to create the basic application, design and implement business objects, and create the database back end. My time = money, both for me and my customers alike so I am sorry if I don't reject all the pro DIV / CSS arguments in favour of cutting costs and providing value for money for my customers. Maybe its just the way that developers minds work, but it seems to me far easier to change a complex table structure than it is to modify DIVs / CSS. Thankfully it now appears that a solution to these issues is now available - its called WPF.

CSS布局通常在可访问性方面要好得多，前提是内容以自然的顺序出现，并且没有样式表也有意义。不仅仅是屏幕阅读器难以适应基于表格的布局:它们也使移动浏览器更难正确呈现页面。

此外，使用基于div的布局，你可以很容易地用打印样式表做一些很酷的事情，比如从打印页面中排除页眉、页脚和导航——我认为这是不可能的，或者至少很难用基于表格的布局做到这一点。

If you're doubting that separation of content from layout is easier with divs than with tables, take a look at the div-based HTML at CSS Zen Garden, see how changing the stylesheets can drastically change the layout, and think about whether you could achieve the same variety of layouts if the HTML was table based... If you're doing a table-based layout, you're unlikely to be using CSS to control all the spacing and padding in the cells (if you were, you'd almost certainly find it easier to use floating divs etc. in the first place). Without using CSS to control all that, and because of the fact that tables specify the left-to-right and top-to bottom order of things in the HTML, tables tend to mean that your layout becomes very much fixed in the HTML.

实际上，我认为完全改变一个基于div和css的设计而不改变div是非常困难的。然而，使用基于div和css的布局，就更容易调整不同块之间的间距以及它们的相对大小。

不幸的是，CSS Zen Garden不能再作为一个好的HTML/CSS设计的例子。实际上，他们最近的所有设计都使用图形作为部分标题。这些图形文件是在CSS中指定的。

因此，一个网站的目的是展示将设计排除在内容之外的优势，现在却经常犯将内容纳入设计的不可言说的罪。(如果HTML文件中的节标题要更改，则显示的节标题不会更改)。

这只能说明，即使是那些提倡严格的DIV和CSS宗教的人，也不能遵循他们自己的规则。你可以用它来指导你如何严格遵守它们。

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。
