Which script would append a new line to a table in "MS Word" 2003?

I have this simple table in MSWord 开发者_高级运维2003:

I want to append one more line to this table:

turtle  dog rooster maple

Which VBScript commands (or set of commands) would I need here to do it automatically?

(I am using "Windows XP")

Here are some notes.

Set wd = CreateObject("Word.Application")

wd.Visible = True

Set doc = wd.Documents.Open ("c:\docs\addtotable.doc")

Set r = doc.Tables(1).Rows.Add

aa = Split("turtle,dog,rooster,maple", ",")

For i = 0 To r.Cells.Count - 1
  r.Cells(i + 1).Range.Text = aa(i)
Next
