Here is another way. An empty cell has a text length = 2. A row marker has a text length = 2. So an empty row with three cells has a text length = 8.
Code:
Sub ScratchMacro()
'A basic Word macro coded by Greg Maxey
Do
If Len(Selection.Tables(1).Rows.Last.Range.Text) = 8 Then
Selection.Tables(1).Rows.Last.Delete
Else
Exit Do
End If
Loop
End Sub
