Removing the padding would be another way to solve the problem. While I do think there is a browser rendering issue here, the bigger problem is with your use case.

Generally speaking, it is a very bad idea to set width of columns in pixels. Best practice is to set the width of the  in pixels (if necessary) and then set the width of its columns using percentages (that add up to 100%). If you do that, the problem also goes away.

Other notes:
 * As Pedro mentioned in the first reply, please use the width property in CSS, not the width HTML attribute.
 * Also, like Pedro mentioned, I would strongly advise removing the infobox class and not using it together with the wikitable class.
 * If you look at your ContractTable talk page, there isn't really any major styling difference between class="wikitable" and class="wikitable infobox", aside from the fact that adding the infobox class floats the table to the right side of the page. Since the infobox class doesn't really add anything substantial, you should just use the wikitable class and add any additional styling yourself as necessary.
 * This type of table that you're creating is not what I would really consider an infobox. An infobox almost always:
 * Floats in the upper right corner of a page
 * Has only 2 columns
 * Has a fairly small width ~300px at most
