you can add Title to you tables:


For i = 1 To ActiveDocument.Tables.Count
ActiveDocument.Tables(i).Title = i & ""
Next


so you can Step Into Code F8:

for i = 1 to ActiveDocument.Tables.Count
ActiveDocuments.Tables(i & "").Select
next

and you can see which tables are being selected.
you can then identify which "i" is to exclude from
emptying the cells.
