quality of a potion Api

Hello, I would like to build a macro or an API script that can be used to determine the quality of a potion. For example, a d100 is rolled and the result is used to calculate how good the quality is that should then be entered in the chat For example, the player rolls a 60 which results in a great healing potion. sorry for my bad english i hope you understand what i mean

Easiest thing would be to create a rollable table with the various potion qualities weighted according to the probability of the result. Then have the player roll on the table with  [[ 1t[TableName] ]] or /roll 1t[TableName]

thx for the help
