OTTOMH, I think adding and editing are lumped together at the moment;
I'll see how difficult it would be to add a config parameter to
disallow adding, too.

Hmm, there's nothing like that, currently, but it may well be possible
to add a hook in the right place that would let you modify the query
about to run, or pass extra criteria to go in the WHERE clause.

What you could do, is use the custom_callbacks option to pass callbacks
to HTML::Table::FromDatabase to modify/skip rows upon output - that'd
be a bit hacky though, as:

 - if you used the download options, you'd get the original data
 - if you were using pagination, filtering out rows at that step would
   throw the pagination out

So, a way to supply additional criteria for the where clause via a hook
may be the way to go.  I'll take a look at that when I have a chance,
but I'm afraid I can't make any guesses as to when that'll be - $work,
and life in general at the moment, is keeping me rather busy!
