Without access to your process to change the part of the code that writes to the cell to replace the cell content rather than add to it, a pre-filled table is not going to be easy to achieve. The best I can manage for the moment is to fill the empty cells using a Word macro.
Code:
Sub FillTable()
Dim oTable As Table
Dim oCell As Cell
Dim oRng As Range
Dim i As Long
If Not ActiveDocument.Tables.Count = 1 Then
MsgBox "Invalid Document"
GoTo lbl_Exit
End If
Set oTable = ActiveDocument.Tables(1)
If Not oTable.Rows.Count = 13 Then 'the number of rows in the table
MsgBox "Invalid Document - Row count = " & oTable.Rows.Count
GoTo lbl_Exit
End If
For i = oTable.Range.Cells.Count To 1 Step -1
Set oCell = oTable.Range.Cells(i)
If Len(oCell.Range) = 2 Then
Set oRng = oCell.Range
oRng.End = oRng.End - 1
oRng.Text = "....................." 'to fill the length of the cell
End If
Next i
lbl_Exit:
Exit Sub
End Sub
