databinding to an array

The code below is very handy for binding to a Datacontrol, Gridview, Dropdownlist etc...Can anyone suggest how a two dimensional array could be used to populate more than one column in a gridview?
Thanks in advance.

Dim custArray As New ArrayList()

custArray.Add("cust1")

custArray.Add("cust2")

custArray.Add("cust3")

GridView1.DataSource = custArray

GridView1.DataBind()
