Tables Not Rendering Correctly in IE9

In the application that I'm working on I discovered that large tables were not rendering correctly in Internet Explorer 9. The same pages displayed correctly in IE8, Firefox, and Google Chrome. My first thought was that there was a problem in my page layout that only affected IE9. I looked over the HTML but couldn't find anything wrong. What I did notice was a large amount of white space. I wondered if that could cause the problem so I added the following to the top of the JSP page to strip out the extra white space.

<%@ page trimDirectiveWhitespaces="true" %>

Problem solved!
