Weird Safari rendering

I'm testing the new template for a we开发者_运维问答bsite that I'm working for, and on Safari I have a really weird behaviour where a piece of page (a table) goes far on the right, about 631 pixels, and I don't have any idea on why this is happening and how to fix it.

Someone can help me? Here the page:

The height of the <a> tags inside your menu is set to 43px. This is too tall, and the box extends below the menu bar. Because your <li>s are float:left, the table "catches" on the last one.

One way to solve this is to add style='clear:both' to the table in question. You could also reduce the height of the <a>s to about 35px.

It looks like your last button 'Redazione' is pushing against the Table content of your main featurelet. Try taking the height sizing off that button. Or you can try displaying your table as a block, which should also work. Odds are, if that button is the issue, your best solution is going to be to make sure that UL becomes the basis for the margin between your navbar and middle content. You should always use a container element to set outward margins, and make sure your elements' dimensions don't extend past their container.
