How can set a var array for tabs?

Hi eveyone,

Is that possible to set a var array for tabs

for instances:

var oneTab = RegExp(“(.+)\\r”)
var twoTab = RegExp(“(.+)\\t(.+)\\r”)
var threeTab = RegExp(“(.+)\\t(.+)\\t(.+)\\r”)
var fourTab = RegExp(“(.+)\\t(.+)\\t(.+)\\t(.+)\\r”)
var firstCol = RegExp(“(.+)”)
var firstTwo = RegExp(“(.+)\\t(.+)”)

if

null + oneTab or twoTab or threeTab or fourTab
insert two tab before

if

firstCol + tab + oneTab or twoTab or threeTab or fourTab
change to firstCol + tab + tab + oneTab or twoTab or threeTab or fourTab

if

firstTwo + oneTab or twoTab or threeTab or fourTab
remain the same

How can I do that?
