The table lists the positions of teams after completion of each round. In order to preserve chronological evolvements, any postponed matches are not included in the round at which they were originally scheduled, but added to the full round they were played immediately afterwards. For example, if a match is scheduled for round 13, but then postponed and played between rounds 16 and 17, it will be added to the standings for round 16.
