Form elements in tables aren't properly read out by screen readers. These programs tend to read out how the textual information on the pages of internet sites was coded. Thus, it would read the labels first before the input boxes. One form element on the pages of your site is fine. But if you had a shitload of form elements on it, you'd be spending more of your time wading through the tons of hatemails! For instance, if you had twenty-something form elements on a page of your internet site in tabular form, a functional screen reader would read the twenty-something labels first before the input boxes.
