// Add players with their scores
leaderboard.addRow({ rank: 1, player: 'Alice', score: 1250, level: 'Master' });
leaderboard.addRow({ rank: 2, player: 'Bob', score: 1180, level: 'Expert' });
leaderboard.addRows([
  { rank: 3, player: 'Charlie', score: 1050, level: 'Advanced' },

]);

// Print the leaderboard
leaderboard.printTable();

You can also put some color to your table like this:

import { Table } from 'console-table-printer';

const p = new Table();
p.addRow({ item: 'Pizza', price: 12.99, rating: '5/5' }, { color: 'red' });
p.addRow({ item: 'Burger', price: 8.99, rating: '4/5' }, { color: 'green' });
p.addRow({ item: 'Ramen', price: 15.99, rating: '5/5' }, { color: 'yellow' });

p.printTable();

You can also put properties based on columns (color/alignment/title)

import { Table } from 'console-table-printer';

const p = new Table({
  title: 'Project Status',
  columns: [
    { name: 'id', alignment: 'left', color: 'blue' },
    { name: 'project', alignment: 'left' },
    { name: 'status', title: 'Current Status' },
  ],
  colorMap: {
    urgent: '\x1b[31m',
    on_track: '\x1b[32m',
  },
});

p.addRow({ id: 1, project: 'Website Redesign', status: 'On Track' }, { color: 'on_track' });
p.addRow({ id: 2, project: 'Mobile App', status: 'Behind Schedule' }, { color: 'urgent' });
p.addRow({ id: 3, project: 'API Integration', status: 'Completed' }, { color: 'green' });

p.printTable();

Table instance creation

3 ways to Table Instance creation:

• Simplest way new Table()

• Only with column names: new Table(['column1', 'column2', 'column3'])

• Detailed way of creating table instance

import { Table } from 'console-table-printer';

new Table({
  title: '📊 Sales Report Q4 2024', // A text showsup on top of table (optional)
  columns: [
    { name: 'region', alignment: 'left', color: 'blue' }, // with alignment and color
    { name: 'sales', alignment: 'right', maxLen: 30 }, // lines bigger than this will be splitted in multiple lines
    { name: 'growth', title: 'Growth %' }, // Title is what will be shown while printing, by default title = name
    { name: 'price', transform: (value) => `$${Number(value).toFixed(2)}` }, // Transform function to format cell values before display
  ],
  rows: [
    { region: 'North America', sales: '$2.5M', growth: '+15%' },
    { region: 'Europe', sales: '$1.8M', growth: '+8%' },
    { region: 'Asia Pacific', sales: '$3.2M', growth: '+22%' },
  ],
  sort: (row1, row2) => row2.sales - row1.sales, // sorting order of rows (optional), this is normal js sort function for Array.sort
  filter: (row) => row.growth > '+10%', // filtering rows (optional)
  enabledColumns: ['region', 'sales'], // array of columns that you want to see, all other will be ignored (optional)
  disabledColumns: ['growth'], // array of columns that you DONT want to see, these will always be hidden
  colorMap: {
    high_growth: '\x1b[32m', // define customized color
  },
  charLength: {
    '👋': 2,
    '😅': 2,
  }, // custom len of chars in console
  defaultColumnOptions: {
    alignment: 'center',
    color: 'red',
    maxLen: 40,
    minLen: 20,
  },
});
