StructuredTextNG and classic structured text have different rules for 
tables, unfortunately.  I have no idea why.

Here are the rules for NG:

Here are the rules for classic:

Note that tables aren't documented in classic stx.  This is probably no 
accident.  Somebody likely added table support to stx classic without 
going through the right steps.  This is not good, but it's life.

The ugly spacing issue I dont know about.

No.

No.  The fact that Page templates' use of StructuredText is broken 
doesn't necessarily mean that structured text is broken (although it may 
be).  We just need to fix the bugs if any.

I'd ask if you could put these issues into the Zope "collector" but its 
been down for a month.  And as soon as I send this mail, this subject is 
*way* gone from my head.  ;-)  I suggest sending bugreports to Ken 
Manheimer, who is working on the new collector:  klm@zope.com.
