I understand what most of the categories are about but I have no idea how good most of the values are.

The above table looks great in a regular browser window and even in WordPress when I am writing the post, but the CSS or whatever is keeping it from displaying properly. Or rather it is displaying it in the way it thinks is proper. So blank lines that are necessary to align categories and values are being surpressed as are the table borders that would make the table so much easier to read. I am not sure WordPress is going to work for the way I like to create blog entries. I want more control over the way my content is going to be displayed that they want to give me.
