Thanks!

Or UA implementor opinions are just not very monolithic on this.  Both 
are possible!

My apologies.  I mixed up my Opera and Safari windows.  Safari puts the 
<table> inside the <a> (and unlike Gecko it doesn't even need a <span>

Fully agreed, and I agree that nested links make for terrible user 
experience, in general.  That's a separate argument from them being hard 
to implement well, though, since the UA has to do something for them
