it is one of the common errors that is made by "webmasters" who write and test their page on msie only...
if you noticed, this page is not "well formed":
it has 3 opening <table> tags, but only 2 closing </table> tags
msie will "auto correct" the problem and display the page just fine
netscape and other stricter browsers will not display it at all, because the page is errorneous
so, to answer your question: add </table> tag where it is supposed to be, check for other missing tags, and republish the page...
(pardon the semi-rant below -- it's directed to public and not to you)
i personally prefer the approach of the stricter browsers, since that means the real, competent, webmasters will be able to design correct pages, rather than producing half-done jobs like many are out there.... there are enough half done pages out there that are costing so much because it will work on some browsers (that are less strict) and not on others :|
and before someone comes and say the problem is "because netscape sucks", save your breath ... this auto correct "feature" that renders the page even if there are mistakes is what is giving us the half-baked webmasters ...
edit: my apology for the mini rant above.... ygpm ....
