Funny thing is that in the process of figuring that out I managed to
implement by myself a cool real-time filter for my table.
I thought this would take ages to do.
Meanwhile, I can't figure out how to implement this thing I thought would
be very simple (have a filter that outputs only tiddlers where a field is
within a certain numerical range).
