Insert and delete columns in a 2d array?

[bleh 1]

Is there an easy way to delete and insert columns in specific rows in a 2d array without affecting the cols of the other rows?

Since my english is not good enough to get across what i need to do, i'm going to post a snippet to help visualize what i need to do:

#include <Array.au3>

Local $avArray[3][4]

$avArray[0][0] = "Col1 Row1"
$avArray[1][0] = "Col1 Row2"
$avArray[2][0] = "Col1 Row3"

$avArray[0][1] = "Col2 Row1"
$avArray[1][1] = "Col2 Row2"
$avArray[2][1] = "Col2 Row3"

$avArray[0][2] = "Col3 Row1"
$avArray[1][2] = "Col3 Row2"
$avArray[2][2] = "Col3 Row3"



_ArrayDisplay($avArray, "Original Array")

;delete a col in a row
$avArray[1][1] = "Col3 Row2"
$avArray[1][2] = ""

_ArrayDisplay($avArray, "Col2 in Row2 removed, Col3 -> Col2, rest untouched")

;insert a col in a row
$avArray[2][2] = "New entry"
$avArray[2][3] = "Col3 Row2"

_ArrayDisplay($avArray, "New entry in Row3 Col3, old Col3 -> Col4")

I hope you understand what i mean.

You can't add columns to specific rows, it's all rows or none.

Well, the "deleted" cols could be filled with nothing.

Edit: Nevermind, i came up with something, i think.
