I am using JabRef with Lyx, and currently when I insert a multi-item citation in my document, it shows up something like this: [8,10,23] in the output, without any space before each item (except for the first one).
I wonder if it is possible to add a space in between item, so in the output it will look like [8, 10, 23]. If so, please let me know how. Thanks!
