For the HTML5 UA requirements see 
http://www.whatwg.org/specs/web-apps/current-work/multipage/section-tree-construction.html#in-table 
in particular the part which reads:

"""If the insertion mode is "in table"[...]

   > A start tag whose tag name is one of: "td", "th", "tr"

     Act as if a start tag token with the tag name "tbody" had been seen, then 
reprocess the current token."""

I believe HTML4 also requires that the tbody be present in the DOM but I'm not 
sure where it says that in the spec.
