I'm trying to picture a room full of <s>people</s> developers agreeing letters are numbers too!

Lets give the little people a slider but lets call it a range!

I really feel like they are trolling.

You start with a neat database table then you engage in an endless struggle trying to allow the user to edit a single row of it. It really feels like you are not suppose to do it. As if it was intended to be as annoying as possible.

E.g. any leading zeros get dropped out of phone number starting with a 0, very common.
