Table
Table ranking rules
 * Four points are awarded for a win.
 * Two points are awarded for a draw.
 * A bonus point is awarded to a team that scores four or more tries in a match or loses a match by seven points or fewer. If a team scores four tries in a match and loses by seven points or fewer, they are awarded both bonus points.
 * Three bonus points are awarded to a team that wins all five of their matches (a Grand Slam). This ensures that a Grand Slam winning team tops the table with a minimum of 23 points – a team could otherwise lose one match but still win two bonus points and win the other four matches with four try bonus points for a maximum of 22 points.
 * Tiebreakers
 * If two or more teams were tied on match points, the team with the better points difference (points scored less points conceded) is ranked higher.
 * If the above tiebreaker failed to separate tied teams, the team that scored the higher number of total tries in their matches is ranked higher.
 * If two or more teams remained tied for first place at the end of the championship after applying the above tiebreakers, the title will be shared between them.
