usage

###cvc

const nvdtb = require(nvdtb);
const Dtb = nvdtb.Cudtb


var dtb = new Dtb(4,'state','anti_state','key','anti_key')
dtb.state = ['undefined','pending','resolved','rejected']
dtb.anti_state = ['undefined','pending','rejeted','resolved']
dtb.key = ['undefined','pending','rslt','exception']
dtb.anti_key = ['undefined','pending','exception','rslt']


> dtb
    state | anti_state |       key |  anti_key
----------------------------------------------
undefined |  undefined | undefined | undefined
----------------------------------------------
  pending |    pending |   pending |   pending

> dtb.cvc('state','resolved','anti_key')
'exception'

###sort

const Dtb = require("./index").Cudtb
var dtb = new Dtb(3,'name','class','year')
dtb.name = ['john','jane','dave']
dtb.class = ['A','B','B']
dtb.year = [15,12,10]

> dtb
name | class | year
