In the Player column we can see the nickname and rating of the player.
The columns labeled Rounds contain information about the player's games in subsequent rounds (e.g. 2+, 4-, 1?). The number represents the position of the opponent in the group/table in that round. The symbol after the number indicates the result/status of the game:

X indicates that the game is unresolved
