What I want to have is pic below,

It's not a real glossary, so no need to introduce Glossary method here.
Tried multiple methods, no luck. Appreciated your instructions and help.

multicolrather than as a table, because then it is easier to sort the input file. Have a look at this answer. – Thruston Jun 15 '15 at 21:59
