我想补充的是，基于div的布局更容易维护、发展和重构。只是在CSS中做了一些改变来重新排序元素，这就完成了。根据我的经验，重新设计使用表的布局是一场噩梦(如果有嵌套的表，则会更糟)。

从语义的角度来看，代码也有意义。

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。

This isn't really about whether 'divs are better than tables for layout'. Someone who understands CSS can duplicate any design using 'layout tables' pretty straightforwardly. The real win is using HTML elements for what they are there for. The reason you would not use tables for non-tablular data is the same reason you don't store integers as character strings - technology works much more easily when you use it for the purpose for which it is desgined. If it was ever necessary to use tables for layout (because of browser shortcomings in the early 1990s) it certainly isn't now.

Try to merge/split a 10/20 something deep colspan/rowspan. More than once I had to supress my instinct to start a fight with someone. [?!] Try to change source code order without changing visible order. [SEO, usability, ...] The very (really simple) page we're looking at is ~150K. I bet It can nearly be halved using proper CSS. [SEO (Yes, SEO, read latest Google specs etc), perfo, ...] Try to make an iterator template that can work in any width. The discussion of the matter in this table-based medium of SO can cause a singularity and destroy us all

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。
