I want to merge 1D arrays. How to change below AutoIt script to access elements as a newly generated 2D array? Test script is :

```
#Include <Array.au3>

Local $_arr1=["name1","addr1","phone1"]
Local $_arr2=["name2","arr2","phone2"]
_make2darray($_arr1,$_arr2)

Func _make2darray($_arr1,$_arr2)
    Local $_2darray=[$_arr1,$_arr2]
    _ArrayDisplay($_2darray)

    _ArrayDisplay($_2darray[0])
    _ArrayDisplay($_2darray[1])

    ConsoleWrite($_2darray[0][0])
EndFunc

```

`$_2darray` output is:

```
Row | Col 0
[0] |{Array}
[1] |{Array}

```

`$_2darray[0]` output is:

```
Row |Col 0
[0] |name1
[1] |addr1
[2] |phone1

```

`$_2darray[1]` output is:

```
Row |Col 0
[0] |name2
[1] |arr2
[2] |phone2

```

But an error occurs accessing the 2D array:

```
ConsoleWrite($_2darray[0][0])
ConsoleWrite(^ ERROR
Exit code: 1    Time: 239.1

```

How can I fix this?
