need some brain power

[Monkuar]

Okay, I have a 3 column table layout on my forum,

 

I want users to beable to select where they want  1 of there profile sections to go under, (and display order) either, left middle or Right side.

 

 

 

See now I can code the javascript/etc ajax to make them update if selected to move to (any direction)

 

But I need help to do it server side, what kind of value/row in my db should i use? just 1 field and use arrays?

Also, let's say I want to move the "Calendar" to the middle or far right, and save that position, what kind of functions would i be working with (in php)

 

I can prob do it  if I use like 200 IF and ELSE conditions, but that would take way to long, any help?
