Tables are invaluable for several functions. The most important to me is
the ability to create a 'block' list that can be easily updated from a
program or script. With a table you just need:
add 00500 unreach port ip from table 86 to any
in your standard configuration and then a script can do:
table 22 add 2001:400:14:23::45
to add a system to the list. To do it without tables means finding an
available rule and inserting the rule in the main table.

I can do it without tables, but it works much better with them.
