The crosstable window shows the tournament crosstable for the current game. Each time you refresh the crosstable window (by pressing its Refresh button, by pressing the Return key in the crosstable window, or by typing Control+Shift+X in the main or game list windows), ChessDB searches for all games in the same tournament as the current game.
Any game played up to three months before or after the current game, with the exact same Event and Site tags, is considered to be in the tournament.
A single left-mouse button click on any result in the crosstable loads the corresponding game. You can add all the games in the tournament to the filter with the Add to filter button in the crosstable window.
The [File] menu lets you print the current table to a file in plain text, LaTeX or HTML table format.
The [Display] menu allows you to choose the table format: All-play-all, Swiss or Knockout or Auto.
The all-play-all format (for round-robin-type events) has a limit of 30 players, but the Swiss format (for tournaments with many players) can display up to 200 players and up to 20 rounds. Auto, which chooses the best format automatically for each tournament, is the default.
Note that ChessDB uses the Round tag of each game to produce a Swiss crosstable, so you will not see any games in the Swiss table for a tournament if its games do not have numeric round values: 1, 2, 3, etc.
The Display menu also lets you customize the data presented to include or exclude ratings, countries and player titles. You can also choose whether color allocations in Swiss tables are displayed.
The Separate score groups option only affects the layout of the table when the players are sorted by score: it causes a blank line to be inserted between each group of players with the same score.
The [Sort] menu allows you to sort the players by name, rating or score; by score is the default.
The [Color] menu lets you turn color (hypertext) display on or off. Since it can take a long time to format and display large crosstables in hypertext, selecting Plain text for large events will save a lot of time. However, in plain text mode you cannot click on players or games.
To get good results with the crosstable, you should mark duplicate games for deletion and your games should have consistent spelling of player, site and event names. See the database maintenance page for help on deleting duplicate games and editing (or spellchecking) player/event/site names.
