I was told by a friend that the order of tables in the IPA chart is not completely arbitrary, but has some motivation to it. In particular, that C tables come before the V table, as features of C production are more readily accessible for speakers, and easier to understand.
Unfortunately, my friend has no idea where she read this, so if this does ring a bell to you, and you have a clue where to look this up in a relevant source, I'd be happy if I could get a reference which I could check.
thanks a lot!
