ascii-table3
Advanced tools
ascii-table3 is a pure ascii table renderer and beautifier, heavily inspired by the ascii-table package created by Beau Sorensen. The original package lacked support for multiple table styles and that is what motivated me to create this new one.
Currently with over a dozen predefined table styles, the collection style keeps growing. I am pretty sure there is a style for everyone. If not, you can even design your own custom style and add it to the library!
This package now includes support for ANSI escape sequences so that rendered tables can output rich console content with colors by relying on packages like chalk.
Please direct any issues, suggestions or feature requests to the ascii-table3 github page.
Existing code for the original ascii-table package should run fine with very few changes (see examples below).
Node.js
var { AsciiTable3 } = require('ascii-table3');
Tables are created programmatically.
var { AsciiTable3, AlignmentEnum } = require('ascii-table3');
// create table
var table =
new AsciiTable3('Sample table')
.setHeading('Name', 'Age', 'Eye color')
.setAlign(3, AlignmentEnum.CENTER)
.addRowMatrix([
['John', 23, 'green'],
['Mary', 16, 'brown'],
['Rita', 47, 'blue'],
['Peter', 8, 'brown']
]);
console.log(table.toString());
+-------------------------+
| Sample table |
+-------+-----+-----------+
| Name | Age | Eye color |
+-------+-----+-----------+
| John | 23 | green |
| Mary | 16 | brown |
| Rita | 47 | blue |
| Peter | 8 | brown |
+-------+-----+-----------+
We can make simpler tables without a title or headings as well.
var table =
new AsciiTable3()
.setAlignCenter(3)
.addRowMatrix([
['John', 23, 'green'],
['Mary', 16, 'brown'],
['Rita', 47, 'blue'],
['Peter', 8, 'brown']
]);
console.log(table.toString());
+-------+----+-------+
| John | 23 | green |
| Mary | 16 | brown |
| Rita | 47 | blue |
| Peter | 8 | brown |
+-------+----+-------+
Tables may be rendered using different styles.
var table =
new AsciiTable3('Sample table')
.setHeading('Name', 'Age', 'Eye color')
.setAlignCenter(3)
.addRowMatrix([
['John', 23, 'green'],
['Mary', 16, 'brown'],
['Rita', 47, 'blue'],
['Peter', 8, 'brown']
]);
// set compact style
table.setStyle('compact');
console.log(table.toString());
-------------------------
Name Age Eye color
------- ----- -----------
John 23 green
Mary 16 brown
Rita 47 blue
Peter 8 brown
These styles range from simple to more elaborate.
table.setStyle('unicode-single');
console.log(table.toString());

Creates new table object.
title - table title (optional)var { AsciiTable3 } = require('ascii-table3');
var table = new AsciiTable3('Data');
Returns wether a val is numeric or not, irrespective of its type.
val - value to checkAsciiTable3.isNumeric('test') // false
AsciiTable3.isNumeric(10) // true
AsciiTable3.isNumeric(3.14) // true
Shortcut to one of the three following methods.
direction - alignment direction (AlignmentEnum.LEFT, AlignmentEnum.CENTER, AlignmentEnum.RIGHT, AlignmentEnum.AUTO)val - string to alignlen - total length of created stringpad - padding / fill char (optional, default ' ')Example:
AsciiTable3.align(AlignmentEnum.LEFT, 'hey', 7) // 'hey '
val - string to alignlen - total length of created stringpad - padding / fill char (optional, default ' ')Example:
AsciiTable3.alignLeft('hey', 7, '-') // 'hey----'
val - string to alignlen - total length of created stringpad - padding / fill char (optional, default ' ')Example:
AsciiTable3.alignCenter('hey', 7) // ' hey '
val - string to alignlen - total length of created stringpad - padding / fill char (optional, default ' ')Example:
AsciiTable3.alignRight('hey', 7) // ' hey'
Attempts to do intelligent alignment of provided val, String input will
be left aligned, Number types will be right aligned.
val - string to alignlen - total length of created stringpad - padding / fill char (optional, default ' ')Example:
AsciiTable3.alignAuto('hey', 7) // 'hey '
Wraps a string into multiple lines of a limited width.
str - string to wrapmaxWidth - maximum width for the wrapped stringAsciiTable3.wordWrap('dummy', 5) // dummy

// t
Truncates a string up to a maximum number of characters (if needed).
str - string to truncatelen - maximum string lenghtExample:
AsciiTable3.truncateString('bananas', 6) // 'ban...'
AsciiTable3.truncateString('apples', 10) // 'apples'
Create a new array at the given len, filled with the given value, mainly used internally.
len - length of arrayval - fill value (optional)Example:
AsciiTable3.arrayFill(4, 0) // [0, 0, 0, 0]
AsciiTable3.arrayFill(2) // [undefined, undefined]

Return the JSON representation of the table, this also allows us to call
JSON.stringify on the instance.
Example:
var table = new AsciiTable3('Title');
table
.setHeading('id', 'name')
.addRow(1, 'Bob')
.addRow(2, 'Steve')

Populate the table from JSON object, should match the toJSON output above.
obj - json objectExample:
