Printing a reasonable table in javascript when it includes ansi escapes

_example output

┌───────────┬────────────────────┬───────┐
│ id        │ name               │ type  │
├───────────┼────────────────────┼───────┤
│ abc123xyz │ something          │ web   │
│ abc124xyz │ something else     │ web   │
│ abc125def │ Martin Luther King │ pserv │
│ abc126xyz │ Abraham Lincoln    │ web   │
└───────────┴────────────────────┴───────┘
