Hey, I found the code below somewhere (sorry, not sure where) a while back:

Sub MergeCols()
Dim FBlank As Boolean
Dim FRow As Integer
FRow = 1
FBlank = IsEmpty(Cells(FRow, 1).Value)
Do While FBlank = False
Rows(FRow + 1 & ":" & FRow + 1).Insert Shift:=xlDown
Cells(FRow, 2).Cut Destination:=Range("A" & FRow + 1)
FRow = FRow + 2
FBlank = IsEmpty(Cells(FRow, 1).Value)
Loop
End Sub


Hope it helps.

Also, I'm doing this within an Excel 2007 Add-in, so I'm not importing an XLS

I'm looking for a fast way to programmatically merge 2 Excel tables into a
third using common column[s] as join keys.

One idea I had is to convert the tables to ADO.NET DataTables and run a SQL
join command on them, then write out the result to Excel.

Does that sound reasonable?

If so, would someone have the syntax to convert Excel tables to ADO
DataTables and back?

Thanks.
