>The whole point of CSS is to take things like width="200px" out of the markup.

I don't see how that's really an improvement in this particular case. In fact, I would say that using 'width="200px"' inline may actually be more readily understandable and maintainable than having the style defined somewhere else and then used only once. (I'm assuming that the 'width="200px"' is not duplicated multiple times in the PHP/Python/Arc/etc code that generates the HTML page. If the same style needs to be identified multiple times in the source code, then of course it may be a better idea to define it once and thereafter refer to it by name.) Are there any practical benefits that I may be missing?

How do you know when you use a style the first time that you'll never use it elsewhere? If you've got many one-off style declarations, you probably don't have a very consistent graphical style.

Besides that, it's nice to know where all your styles live instead of having to grep your whole project. And inline styles take precedence over everything else, so mixing them with stylesheets can create havoc.

The example is contrived because there is no content in the table cells. In the real world there will be some content, and suddenly your "width"-attributes are many lines apart and not nicely aligned. This makes is a mess to maintain, because there is no single place where your layout is defined; the information is spread all over the document, mixed with other kinds of information.

Furthermore, separating style info into a style sheet allows you to adapt the style for different devices.
