' This allows adding rows on the fly....Tested and it works!

Dim multiList As New List(Of List(Of String))
Dim ListRow As Integer = 0

For each record in some_source 
  dim Country as string = record.country 'from some source 
  dim Date as Date = record.Date 'from some source 
  dim Venue as string = record.Venue 'from some source 
  dim Attendance as string = record.Attendance 'from some source 

  multiList.Add(New List(Of String))
  multiList(ListRow).Add(Country)
  multiList(ListRow).Add(Date)
  multiList(ListRow).Add(Venue)
  multiList(ListRow).Add(Rating)
  multiList(ListRow).Add(Attendance)
  ListRow = ListRow + 1
next

If you want to use ArrayList, just make it's items contain other ArrayLists.

Or you could use normal arrays as:

Dim multiArray(2, 2) As String
multiArray(0, 0) = "item1InRow1"
multiArray(0, 1) = "item2InRow1"
multiArray(1, 0) = "item1InRow2"
multiArray(1, 1) = "item2InRow2"

Though my personal preference would be to use List as:

Dim multiList As New List(Of List(Of String))
multiList.Add(New List(Of String))
multiList.Add(New List(Of String))

multiList(0).Add("item1InRow1")
multiList(0).Add("item2InRow1")
multiList(1).Add("item1InRow2")
multiList(1).Add("item2InRow2")

Edit: How to find row:

Dim listIWant As List(Of String) = Nothing
For Each l As List(Of String) In multiList
    If l.Contains("item1InRow2") Then
        listIWant = l
        Exit For
    End If
Next
