[Zope] My first question.

[Goldthwaite, Joe]

Son of a..., that worked!  I don't understand it.

 <b tal:omit-tag="python:item.Flags!='B'" tal:content="item/desc" />

Does this rely on the " />" at the end to close the B tag or does the tal
interpreter close it automatically?

It's invalid xhtml to have <b><td>stuff</td></b>
Inside a table row, the only allowable elements are (correct me if I'm
wrong) td and th.

I would try something like (untested):

<td>
 <b tal:omit-tag="python:item.Flags!='B'" tal:content="item/desc" />
</td>

This way, you're putting <b> inside the table cell.  If item.Flags is
not 'b', then item/desc will not be bold.

It's actually fairly easy in TAL once you get the hang of it ;-)

For complicated lists and such, I sometimes use python to generate the
html.  Just use the best tool for the job.

I think using zpt and/or DTML along with python gives you a better
design approach.  You can see what each piece (presentation, business
logic) is doing better when they are separated!

HTH,
