I have two table cells. The first contains a link and an image (“CollegiateLink”). The second contains a form with an image for the submit button (“Pay Dues”):

In Firefox and IE, the cells have unwanted padding as shown above. In Chrome they appear fine. Why is this?
Here’s the source for the table row:

I can’t use an image map because the “Pay Dues” image is a form element, not an anchor tag. I’ve tried explicitly setting the td heights with no success. Any ideas?
You could merge the two

Try this:
