You can also create a Table instance and print it:

const { Table } = require('console-table-printer');

//Create a table
const p = new Table();

// add rows with color
p.addRow({ Record: 'a', text: 'red wine please', value: 10.212 });
p.addRow({ Record: 'b', text: 'green gemuse please', value: 20.0 });
p.addRows([
  // adding multiple rows are possible
  { Record: 'c', text: 'gelb bananen bitte', value: 100 },
  { Record: 'd', text: 'update is working', value: 300 },
]);

//print
p.printTable();

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

const p = new Table();
p.addRow({ description: 'red wine', value: 10.212 }, { color: 'red' });
p.addRow({ description: 'green gemuse', value: 20.0 }, { color: 'green' });
p.addRow({ description: 'gelb bananen', value: 100 }, { color: 'yellow' });
p.printTable();

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

const p = new Table({
  columns: [
    { name: 'id', alignment: 'left', color: 'blue' }, // with alignment and color
    { name: 'text', alignment: 'right' },
    { name: 'is_priority_today', title: 'Is This Priority?' }, // with Title as separate Text
  ],
  colorMap: {
    custom_green: '\x1b[32m', // define customized color
  },
});

p.addRow({ id: 1, text: 'red wine', value: 10.212 }, { color: 'green' });
p.addRow(
  { id: 2, text: 'green gemuse', value: 20.0 },
  { color: 'custom_green' } // your green
);
p.addRow(
  { id: 3, text: 'gelb bananen', value: 100, is_priority_today: 'Y' },
  { color: 'yellow' }
);
p.addRow({ id: 3, text: 'rosa hemd wie immer', value: 100 }, { color: 'cyan' });

p.printTable();

CLI

There is also a CLI tool for printing Tables on Terminal directly table-printer-cli

Table instance creation

3 ways to Table Instance creation:

1. Simplest way new Table()

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

3. Detailed way of creating table instance

new Table({
  title: 'Title of the Table', // A text showsup on top of table (optoinal)
  columns: [
    { name: 'column1', alignment: 'left', color: 'red' }, // with alignment and color
    { name: 'column2', alignment: 'right', maxLen: 30 }, // lines bigger than this will be splitted in multiple lines
    { name: 'column3', title: 'Column3' }, // Title is what will be shown while printing, by default title = name
  ],
  rows: [{ column1: 'row1' }, { column2: 'row2' }, { column3: 'row3' }],
  sort: (row1, row2) => row2.column1 - row1.column1, // sorting order of rows (optional), this is normal js sort function for Array.sort
  filter: (row) => row.column1 < 3, // filtering rows (optional)
  enabledColumns: ['column1'], // array of columns that you want to see, all other will be ignored (optional)
  disabledColumns: ['column2'], // array of columns that you DONT want to see, these will always be hidden
  colorMap: {
    custom_green: '\x1b[32m', // define customized color
  },
  charLength: {
    '👋': 2,
    '😅': 2,
  }, // custom len of chars in console
});

Functions

• addRows(rowObjects, options) adding multiple rows. array of row object. This case options will be applied to all the objects in row
• addColumn(columnObject) adding single column
• addColumns(columnObjects) adding multiple columns
• printTable() Prints the table on your console
