<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I’m developing a dynamic ZPT that builds a table
dynamically from an external database. I’d like to create a table row
with at most two columns. The condition is that if there is an odd number
of data, the last table row will only contain one <td>. If there is
an even number of data, then the last table row will contain two
<td>’s. Sounds pretty simple right? Just create a condition
on the closing </tr> tag….well as I have found out, it’s not
so simple in TAL.</span></font></p>

because Zope will treat it as invalid HTML since the opening <tr> tag
will not have a closing </tr> tag. This really makes simple tasks
such as mine very complex now.</span></font></p>
