Ascii Table
Easy table output for node debugging, but you could probably do more with it,
since its just a string.

Usage
Node.js
var AsciiTable = require('ascii-table')
Browser
<script src="ascii-table.min.js"></script>
Note: If using in the browser, it will be placed under window.AsciiTable
Example
Basic usage
var table = new AsciiTable('A Title')
table
.setHeading('', 'Name', 'Age')
.addRow(1, 'Bob', 52)
.addRow(2, 'John', 34)
.addRow(3, 'Jim', 83)
console.log(table.toString())
.----------------.
| A Title |
|----------------|
| | Name | Age |
|---|------|-----|
| 1 | Bob | 52 |
| 2 | John | 34 |
| 3 | Jim | 83 |
'----------------'
We can make a simple table without a title or headings as well.
var table = new AsciiTable()
table
.addRow('a', 'apple', 'Some longer string')
.addRow('b', 'banana', 'hi')
.addRow('c', 'carrot', 'meow')
.addRow('e', 'elephants')
console.log(table.toString())
.------------------------------------.
| a | apple | Some longer string |
| b | banana | hi |
| c | carrot | meow |
| e | elephants | |
'------------------------------------'
API
Static Methods
AsciiTable
See: AsciiTable.factory for details on instantiation
AsciiTable.factory([title], [options])
Table instance creator
title - table title (optional, default null)options - table options (optional)
prefix - string prefix to add to each line on render
Note: If an object is passed in place of the title, the fromJSON
method will be used to populate the table.
Example:
var table = AsciiTable.factory('title')
var table = AsciiTable.factory({
title: 'Title'
, heading: [ 'id', 'name' ]
, rows: [
[ 1, 'Bob' ]
, [ 2, 'Steve' ]
]
})
AsciiTable.align(direction, val, len, [pad])
Shortcut to one of the three following methods
direction - alignment direction (AsciiTable.LEFT, AsciiTable.CENTER, AsciiTable.RIGHT)val - string to alignlen - total length of created stringpad - padding / fill char (optional, default ' ')
Example:
table.align(AsciiTable.LEFT, 'hey', 7) // 'hey '
AsciiTable.alignLeft(val, len, [pad])
val - string to alignlen - total length of created stringpad - padding / fill char (optional, default ' ')
Example:
table.alignLeft('hey', 7, '-') // 'hey----'
AsciiTable.alignCenter(val, len, [pad])
val - string to alignlen - total length of created stringpad - padding / fill char (optional, default ' ')
Example:
table.alignCenter('hey', 7) // ' hey '
AsciiTable.alignRight(val, len, [pad])
val - string to alignlen - total length of created stringpad - padding / fill char (optional, default ' ')
Example:
table.alignRight('hey', 7) // ' hey'
AsciiTable.alignAuto(val, len, [pad])
Attempt 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:
table.align(AsciiTable.LEFT, 'hey', 7) // 'hey '
AsciiTable.arrayFill(len, [val])
Create a new array at the given len, filled with the given value, mainly used internally
len - length of arrayval - fill value (optional)
Example:
AsciiTable.arrayFill(4, 0) // [0, 0, 0, 0]
Instance Methods
instance.setBorder([edge], [fill], [top], [bottom])
Set the border characters for rendering, if no arguments are passed it will be
reset to defaults. If a single edge arg is passed, it will be used for all borders.
edge - horizontal edges (optional, default |)fill - vertical edges (optional, default -)top - top corners (optional, default .)bottom - bottom corners (optional, default ')
Example:
var table = new AsciiTable('Stars')
table
.setBorder('*')
.setHeading('oh', 'look')
.addRow('so much', 'star power')
console.log(table.toString())
************************
* Stars *
************************
* oh * look *
************************
* so much * star power *
************************
instance.removeBorder()
Example:
table.removeBorder()
console.log('' + table)
# Fruit Thing
--- ----------- --------------------
a apple Some longer string
b banana hi
c carrot meow
e elephants
instance.setAlign(idx, direction)
idx - column index to aligndirection - alignment direction, (AsciiTable.LEFT, AsciiTable.CENTER, AsciiTable.RIGHT)
Example:
table
.setAlign(2, AsciiTable.RIGHT)
.setAlign(1, AsciiTable.CENTER)
console.log(table.toString())
.-------------------------------------.
| a | apple | Some longer string |
| b | banana | hi |
| c | carrot | meow |
| e | elephants | |
'-------------------------------------'
instance.setAlignLeft(idx)
Alias to instance.setAlign(idx, AsciiTable.LEFT)
instance.setAlignCenter(idx)
Alias to instance.setAlign(idx, AsciiTable.CENTER)
instance.setAlignRight(idx)
Alias to instance.setAlign(idx, AsciiTable.RIGHT)
instance.setTitle(title)
Example:
var table = new AsciiTable('Old Title')
table.setTitle('New Title')
instance.getTitle()
Get the current title of the table
Example:
table.getTitle() // 'New Title'
instance.setTitleAlign(direction)
direction - table alignment direction
Example:
instance.setTitleAlignLeft()
Alias to instance.setTitleAlign(AsciiTable.LEFT)
instance.setTitleAlignCenter()
Alias to instance.setTitleAlign(AsciiTable.CENTER)
instance.setTitleAlignRight()
Alias to instance.setTitleAlign(AsciiTable.RIGHT)
instance.sort(iterator)
iterator - sorting method to run against the rows
Example:
table.sort(function(a, b) {
return a[2] - b[2]
})
console.log(table.toString())
.----------------.
| 2 | John | 34 |
| 1 | Bob | 52 |
| 3 | Jim | 83 |
'----------------'
instance.sortColumn(index, iterator)
Sorting shortcut for targeting a specific column
index - column idx to sortiterator - sorting method to run against column values
Example:
// This is quivalent to the `sort` example above
table.sortColumn(2, function(a, b) {
return a - b
})
instance.setHeading(heading, [...])
Set the column headings for the table, takes arguments the same way as addRow
heading - heading array or arguments
Example:
table.setHeading('ID', 'Key', 'Value')
// or:
table.setHeading(['ID', 'Key', 'Value'])
instance.setHeadingAlign(direction)
Example:
instance.setHeadingAlignLeft()
Alias to instance.setHeadingAlignLeft(AsciiTable.LEFT)
instance.setHeadingAlignCenter()
Alias to instance.setHeadingAlignLeft(AsciiTable.CENTER)
instance.setHeadingAlignRight()
Alias to instance.setHeadingAlignLeft(AsciiTable.RIGHT)
instance.addRow(row, [...])
Rows can be added using a single array argument, or the arguments if multiple
args are used when calling the method.
row - array or arguments of column values
Example:
var table = new AsciiTable()
table
.addRow(1, 'Bob', 52)
.addRow([2, 'John', 34])
console.log(table.render())
.---------------.
| 1 | Bob | 52 |
| 2 | John | 34 |
'---------------'
instance.addRowMatrix(rows)
Bulk addRow operation
rows - multidimentional array of rows
Example:
table.addRowMatrix([
[2, 'John', 34]
, [3, 'Jim', 83]
])
instance.setJustify(enabled)
Justify all columns to be the same width
enabled - boolean for turning justify on or off, undefined considered true
Example:
table
.addRow('1', 'two', 'three')
.setJustify()
console.log(table.toString())
.-----------------------.
| 1 | two | three |
'-----------------------'
instance.toString()
Render the instance as a string for output
Alias: [valueOf, render]
instance.toJSON()
Return the JSON representation of the table, this also allows us to call
JSON.stringify on the instance.
Example:
var table = new AsciiTable('Title')
table
.setHeading('id', 'name')
.addRow(1, 'Bob')
.addRow(2, 'Steve')
console.log(table.toJSON())
console.log(JSON.stringify(table))
{
title: 'Title'
, heading: [ 'id', 'name' ]
, rows: [
[ 1, 'Bob' ]
, [ 2, 'Steve' ]
]
}
{"title":"Title","heading":["id","name"],"rows":[[1,"Bob"],[2,"Steve"]]}
instance.fromJSON(obj)
Populate the table from json object, should match the toJSON output above.
Alias: [parse]
Example:
var table = new AsciiTable().fromJSON({
title: 'Title'
, heading: [ 'id', 'name' ]
, rows: [
[ 1, 'Bob' ]
, [ 2, 'Steve' ]
]
})
instance.clear()
Clear / reset all table data
Alias: [reset]
instance.clearRows()
Reset all row data, maintains title and headings.
Install
With npm
npm install ascii-table
