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.

我想使用表格元素进行布局确实与表格数据没有什么关系。那又怎样?我的老板在乎吗?我的用户关心吗?

谷歌和其他自动化系统确实关心这些问题，而且它们在许多情况下同样重要。语义代码对于非智能系统来说更容易解析和处理。

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.

下面是我的程序员在一个类似的帖子中给出的答案

语义101

首先看一下这段代码，想想哪里出了问题……

class car {
    int wheels = 4;
    string engine;
}

car mybike = new car();
mybike.wheels = 2;
mybike.engine = null;

当然，问题在于自行车不是汽车。car类对于bike实例是不合适的类。代码没有错误，但是语义不正确。这对程序员的形象很不利。

语义102

现在将此应用于文档标记。如果您的文档需要显示表格数据，那么适当的标记将是<table>。但是，如果将导航放在表中，则滥用了<table>元素的预期用途。在第二种情况下，您没有表示表格数据—您(mis)使用<table>元素来实现表示目标。

结论

游客会注意到吗?不。你的老板在乎吗?也许吧。作为程序员，我们有时会偷工减料吗?当然。但是我们应该吗?不。如果使用语义标记，谁会受益?你，还有你的职业声誉。现在去做正确的事吧。

对我来说，一个巨大的问题是，表，特别是嵌套表，需要更长的时间来呈现比一个正确布局的css实现。(你可以让css一样慢)。

所有浏览器呈现css的速度都更快，因为每个div都是一个单独的元素，所以用户在阅读时可以加载屏幕。(对于庞大的数据集等)。我在那个实例中使用了css而不是表格，甚至没有处理布局。

嵌套的表(单元格中的表等)直到找到最后一个“/table”才会呈现到浏览器窗口。更糟糕的是，定义不清的表有时甚至无法呈现!或者当它发生的时候，事情就会不正常。(没有正确地与“TD”等共进)

我在大多数情况下使用表格，但当涉及到大数据和希望为最终用户快速呈现屏幕时，我尽最大努力利用CSS所提供的东西。
