The following code will identify the non-system tables:
Sub ListTables()
Dim dbCurr As DAO.Database
Dim tdfCurr As DAO.TableDef
Set dbCurr = CurrentDb()
For Each tdfCurr In dbCurr.TableDefs
If (tdfCurr.Attributes And dbSystemObject) = 0 Then
Debug.Print tdfCurr.name
End If
Next tdfCurr
Set dbCurr = Nothing
