Reasonable deflection for a metal and wood table
I've been tasked with building a couple of tables for a church.
The "customer" is requesting that the tables be made from 3" high x 1.5" wide by 14 ga. tube steel, with a wood plank top.

The table will be 12' long, with a leg (same size tube) in each corner.
I'm prone to 'run the numbers' on pretty much everything I do,
so, using the calculators available on this site, I've come up with various potential deflections.
Which begs the question, "What is a reasonable amount of deflection for this application?".
Without having any good reason, I've chosen L/240.
