I have a lot of experience with these adjustable folding table legs and a lot of experience playing EFL on these table legs (9 years and counting now).
If your table legs are adjustable (i.e. you can change the height which is what I'm assuming you're talking about in your post) Instead of looking for a standard height to play on, why not focus on the word "adjustable" in the table leg and you and the guy you're playing against adjust the table height to what you both are comfortable with, it's takes less than a minute to adjust them. It's a very dynamic concept!!
Another thought, if it's your board and you're the home team, you set it to what you're most comfortable with and make the other coach adjust.
Good luck!
