### Fixed Column Width

Say I have two lists `a`

and `b`

: `a = [1,'boy','tree']`

and `b = ['mathematics','is','fun']`

.

How can I display this evenly spaced like below? (can someone please edit the below so that there is actually evenly spaced columns, as the editor is deleting the spacing)

`1 boy `~~ boy ~~ tree
mathematics is fun
