table-layout

Generates plain-text tables from JSON recordset input (array of objects). Useful for presenting text in column layout or data in table layout in text-based user interfaces. Also available as a command-line tool.

Synopsis

Where input looks like this:

[
  {
    "number": 15134,
    "title": "Coveralls has no source available ",
    "login": "ndelangen",
    "comments": 0
  },
  {
    "number": 15133,
    "title": "Fixing --preserve-symlinks. Enhancing node to exploit.",
    "login": "phestermcs",
    "comments": 0
  },
  {
    "number": 15131,
    "title": "Question - Confused about NPM's local installation philosophy",
    "login": "the1mills",
    "comments": 0
  },
  {
    "number": 15130,
    "title": "Question - global npm cache directory if user is root?",
    "login": "ORESoftware",
    "comments": 0
  }
]

This code...

const Table = require('table-layout')
const issues = require('./issues.json')
const table = new Table(issues, { maxWidth: 60 })
console.log(table.toString())

...produces this output:
