i found this code but i cant figure out how to make it work for multiple
columns
for example on this sheet.

name Date
charlie 7-27-07
zach 8-20-07

Private Sub Worksheet_Change(ByVal Target As Range)
Dim MyData As String
Dim OldData As Range
Dim NewData As Range
Dim Nms, r As Long

'Determine rangename containing target
Set Nms = ActiveWorkbook.Names
For r = 1 To Nms.Count
If Not Intersect(Target, Range(Nms(r))) Is Nothing Or _
Not Intersect(Target.Offset(-1), Range(Nms(r))) Is Nothing Then
MyData = Nms(r).Name
Exit For
End If
Next

Set OldData = Range(MyData)
'Check if target is in existing range or cell below
If Not Intersect(Target, OldData) Is Nothing Then
Set NewData = OldData 'In existing range
ElseIf Not Intersect(Target, OldData.Offset(1)) Is Nothing Then
Set NewData = Union(OldData, OldData.Offset(1)) 'Below existing range
Else
Exit Sub 'Not in data region
End If
'Sort Data
NewData.Sort Key1:=NewData.Cells(1), Order1:=xlAscending,
Key2:=NewData.Cells(1), Order2:=xlAscending, Header:=xlNo, _
OrderCustom:=1, MatchCase:=False, Orientation:=xlTopToBottom
'Reset range name
ActiveWorkbook.Names.Add Name:=MyData, RefersTo:="=" & ActiveSheet.Name
& "!" & _
Range(NewData.Cells(1), NewData.Cells(1).End(xlDown)).AddressLocal

Set Nms = Nothing
Set OldData = Nothing
Set NewData = Nothing
End Sub
