Hrm... the HTML spec allows for TABLE to be inside FORM.  In fact, it's 
your INPUT tag that violates the spec, but everyone puts inputs directly 
in the form.  They're supposed to go inside some block tag like a <p> or 
a <fieldset> or something... (don't get me started about the spec :)

The Seaside parser doesn't enforce any of those rules, it allows any 
block tag (except another form), inline tag, or script tag.  So not sure 
why moving that <table> had any effect except that, well, Netscape and 
tables...  don't get me started on that either :)

Well, you can place <button>'s without a form I think, but you can't 
make them do anything.  I believe the only things that can submit 
(without javascript) are <a>, <form>, <area>, or <img ismap>.  So you 
can have an image inside an anchor or use an image with an image map. 
But that probably isn't any nicer than having a small form with a button 
in it :)
