Matching fight using weight as indicator

I'm building a matching system where they get match by weight with a if statement from vb and getting the registered information from the database, Example:

1. User A enters 0lb and 5oz for the weight difference

2. After clicking a button they would appear like that but in datagridview

3. And all of the teams and players are in database

All of the registered teams would get matched with their player Example:

this would be a result of the code:

Ateam|Aplayer1|90lb|50oz | Bteam|Bplayer2|90lb|55oz
Ateam|Aplayer2|90lb|45oz | Bteam|Bplayer3|90lb|40oz
Ateam|Aplayer3|90lb|30oz | Bteam|Bplayer1|90lb|35oz

I don't have the slightest idea how to make them into one single row thank you for your help

heres the database here it is I hope u guys can make something out if this thank you
