I don't understand what the problem is. You have not mention the formatting that you have been attempting, other than listed table. Listed table is probably not the way to go because that format is for tables. Pronunciation keys are generally not treated as a table. There is even a separate section just for Pronunciation. You didn't say if you had looked there. If you wouldn't mind, take a look at 21.7, scroll down and look at all the examples. Let us know if you find anything helpful there.
