Yes, you should be able to find it in the mailing list archives...
The dynamic tables features of Embperl detected the end of the table/row
when an expression, which contains $rwo/$col is undefined. This is the case
when the column contains NULL.

I actually answered this offline, because I didn't have time to
check. But if you run into this, just do the following.
[+ $foo[$row] || ' ' +]
and the expression won't fail. Obviously you shouldn't do this on
all the fields in a row, but if you have some which are allowed to be
null, this will work.

I'm not sure which upsets me more: that people are so unwilling to accept
responsibility for their own actions, or that they are so eager to regulate
everyone else's.
