I've been hacking away yesterday at "yet another HTML builder" lib
which would probably be useful here:

Example usage:

This is intended to be used in the various places in Trac where we
generate little HTML snippets.
I like it very much!
I tried it for my moderately complex TracIni macro,
and it nearly worked out-of-the-box.
A few suggestions:
* add an easy way to add list of nodes.
Fragment.__get_item__ should accept iterable,
as in the example below (TBODY(rows))
* make it easy to play well with wiki_to_... functions
Fragment.append should know about Markup,
so that a Markup object doesn't get converted
to a string before being escaped.in order

1) excerpt of TracIni macro which creates an HTML table:
...
rows = []
for section, configs, section_doc in default_config:
...
row = TR()[TH(rowspan=nconfigs*2)[section]]
for name, value, since, doc in configs:
...
html_doc = wiki_to_html(doc, self.env, req)
row.append(TD(class_="name")[name])
row.append(TD(class_="defaultvalue")[value])
rows.append(row)
rows.append(TR()[TD(colspan="2", class_="doc")[html_doc]])
row = TR()
if not rows:
return ''
add_stylesheet(req, 'common/css/about.css')
return str(DIV(class_="about_config")[
TABLE()[THEAD()[TR()[TH(class_="section")["Section"],
TH(class_="name")["Name"],
TH(class_="defaultvalue")["Default
Value"]]],
TBODY()[rows]]])
2) patch to html.py which is needed by the above code
