How to automatize a scoring table for tennis table competition?

Good morning to the community.
I am working on the file "Scoing Table Tennis Table".
I would like to create a tournament for tennis table.
I would like to automatize the process to make the scoring table for a competition.
In the exemple, in the table A1:E5, the player 1 loses against the player 2 (9-11), wins against the player 3 (11-2), loses against the player 3 (10-12).
The table located in the table range J8:012 represents the cumulative score of game1 and game2.

I would like to add player (player 5, 6) and have a table ranking that change with this supplements of players. I would like for exemple to add player 5 in J6 and J13.
I would like to have an update of the score when I enter a new score. I would like for exemple that the table located can cumulate the score of many games (game 1, game 2, game3).

Thank you for your help.
