table headings misaligned

I had the same Problem. I overwrote the following theme-function.

Hey folks, I did run into this myself the other day but didn't have time to work out the problem. It looks like what I need to do is make the lines like this one: $rows[$delta]['suffix'] = ''; contingent on the existence of the same field in the preferred name and visa versa. The rest of the changes to macco's code are customizations and not the bug fix - for anyone that didn't catch that.

BTW, the recommended way to customize theme functions is to put copy them to one of your theme's file and change it there instead of changing the one provided with the module. And as for CSS, the recommended practice for changing, or eliminating CSS is to override it in your theme's style.css file (or other). See the Drupal handbooks on theming for more info.

Anyway, this is the proper fix, sorry it isn't a patch (I don't have time right now):

 * Display the input fields to the user.
 * 
 * @param array $form
 * 	The data to be rendered.
 * @return string An HTML string ready for display.

I tested it by requiring the legal name, setting the preferred name to don't use, then using only the first, middle, and last name of the legal name, and requiring only the first and last name. Pre-changes, it was messed up. Post-changes it was fixed.

Thanks for the issue post. I'll get this out in a new release later today.
