我将一个接一个地看你的论点，并试着指出其中的错误。
将内容与布局分开是很好的
但这是一个错误的论点;陈词滥调的思考。
It's not fallacious at all because HTML was designed intentionally. Misuse of an element might not be completely out of question (after all, new idioms have developed in other languages, as well) but possible negative implications have to be counterbalanced. Additionally, even if there were no arguments against misusing the <table> element today, there might be tomorrow because of the way browser vendors apply special treatment to the element. After all, they know that “<table> elements are for tabular data only” and might use this fact to improve the rendering engine, in the process subtly changing how <table>s behave, and thus breaking cases where it was previously misused.
那又怎样?我的老板在乎吗?我的用户关心吗?
视情况而定。你的老板是尖头发吗?那他可能不在乎。如果她有能力，那么她就会在乎，因为用户会在乎。
也许我或我的开发伙伴谁必须维护一个网页关心…表是否更难维护?我认为使用表格比使用div和css更容易。
大多数专业的web开发人员似乎反对你[需要引用]。事实上，表的可维护性较差，这是显而易见的。使用表格进行布局意味着更改公司布局实际上意味着更改每个页面。这可能会非常昂贵。另一方面，明智地将语义上有意义的HTML与CSS结合使用可能会将此类更改限制在CSS和所使用的图片上。
顺便说一下……为什么使用div或span可以很好地将内容与布局分开，而不是表格?只有div的良好布局通常需要大量嵌套的div。
深度嵌套<div>是反模式，就像表布局一样。优秀的网页设计师不需要太多这样的东西。另一方面，即使是这样深嵌套的div也没有很多表布局的问题。事实上，它们甚至可以通过逻辑地将内容划分为多个部分来构成语义结构。
代码的可读性
我觉得正好相反。大多数人懂html，很少人懂css。这是简单的。
“大多数人”不重要。专业人士。对于专业人士来说，表格布局比HTML + CSS带来更多的问题。这就像是说我不应该使用GVim或Emacs，因为记事本对大多数人来说更简单。或者我不应该使用LaTeX，因为MS Word对大多数人来说更简单。
SEO最好不要使用表格
我不知道这是不是真的，也不会把它作为一个论点，但它是合乎逻辑的。搜索引擎搜索相关数据。虽然表格数据当然可能是相关的，但它很少是用户搜索的内容。用户搜索页面标题或类似突出位置中使用的术语。因此，将表格内容排除在过滤之外，从而大幅减少处理时间(和成本!)是合乎逻辑的。
表比较慢。
必须插入一个额外的tbody元素。这对于现代网络浏览器来说是微不足道的。
额外的元素与表变慢无关。另一方面，表的布局算法要困难得多，浏览器通常必须等待整个表加载后才能开始布局内容。此外，缓存布局将不起作用(CSS可以很容易地缓存)。所有这些都在前面提到过。
向我展示一些使用表会显著降低页面速度的基准测试。
不幸的是，我没有任何基准测试数据。我自己也会感兴趣，因为这个论点确实缺乏一定的科学严谨性。
大多数需要升级的网站也需要新的内容(html)。一个新版本的网站只需要一个新的css文件的场景是不太可能的。
Not at all. I've worked on several cases where changing the design was simplified by a separation of content and design. It's often still necessary to change some HTML code but the changes will always be much more confined. Additionally, design changes must on occasion be made dynamically. Consider template engines such as the one used by the WordPress blogging system. Table layouts would literally kill this system. I've worked on a similar case for a commercial software. Being able to change the design without changing the HTML code was one of the business requirements.
Another thing. Table layout makes automated parsing of websites (screen scraping) much harder. This might sound trivial because, after all, who does it? I was surprised myself. Screen scraping can help a lot if the service in question doesn't offer a WebService alternative to access its data. I'm working in bioinformatics where this is a sad reality. Modern web techniques and WebServices have not reached most developers and often, screen scraping is the only way to automate the process of getting data. No wonder that many biologists still perform such tasks manually. For thousands of data sets.
