How would I move a key in a table to a different array?

local Tab = {Xd = 'G', ge  = 'g',ce = 'gg',keke = '1', fefe = '2'}


What if I wanted to move Xd to first 
and ge to last 

what would I do?

You can pretty easily reference the values that you wanna put into the other table and just copy em' over. You can do it like so:

local newtbl = {}
local Tab = {Xd = 'G', ge  = 'g',ce = 'gg',keke = '1', fefe = '2'}

newtbl.Xd = Tab.Xd
newtbl.ge = Tab.ge

Or, if you're converting the table into a regular old array, you can use table.insert() and it will automatically insert it for you, in order.

local newtbl = {}
local Tab = {Xd = 'G', ge  = 'g',ce = 'gg',keke = '1', fefe = '2'}

table.insert(newtbl,Tab.Xd)
table.insert(newtbl,Tab.ge)

Hope this helps! If you have any further questions feel free to comment or look things up on the devforum.
