I have two almost identical pages in IE, one works and the other doesn't

Subject: I have two almost identical pages in IE, one works and the other doesn't
Posted by:  Luminari (LuminariG…@gmail.com)

I have two pages.  Both of them are supposed to have one table on it
with a fixed header. Both pages were tested in IE6.  Structurally they
are identical.  Both have a <div> that wraps a <table> that has a
<thead> and a <tbody>.  In the first example, the <thead> stays fixed
at the top of the div as it scrolls.  In the second example the
<thead> scrolls away.  Could anyone tell me what about the second page
makes it not work?

Thanks
