Help adding rows to table in template?

I'm trying to insert data into a dynamic table in a template, but I don't seem to be able to add new rows. As a result, my table has one row containing the last list item.

To test the procedure I've written the code below, and the Word template I'm using is attached here if required: Attachment 8119

The problem might be how I'm calling the .Rows.Add routine. I'm quite new at this and still wrapping my head around all the hierarchy.

Any help would be greatly appreciated.

' Launch Word and load the template
Set objWord = New Word.Application
objWord.Documents.Add "C:\Users\Chris\Desktop\BMS-0900-011-02.dotx"
objWord.Visible = True

'How many documents are there?
Dim numDTDocs As Integer
numDTDocs = 5

' Create list of transmitted documents

ReDim TransmittalList(1 To numDTDocs * 3) As String

For i = 1 To numDTDocs
TransmittalList(3 * i - 2) = "Document " & Str(i) & Chr(14)
TransmittalList(3 * i - 1) = "Description " & Str(i) & Chr(14)
TransmittalList(3 * i - 0) = "1" & Chr(14)

End With

If i < numDTDocs Then
objWord.ActiveDocument.Tables(1).Rows.Add
