Description

Configuration options let you heavily customize your Handsontable instance. For example, you can:

Enable and disable built-in features
Enable and configure additional plugins
Personalize Handsontable's look
Adjust Handsontable's behavior
Implement your own custom features

To apply configuration options, pass them as a second argument of the Handsontable constructor, using the object literal notation (opens new window):

Read more on the Configuration options page.

const container = document.getElementById('example');

const hot = new Handsontable(container, {
  // configuration options, in the object literal notation
  licenseKey: 'non-commercial-and-evaluation',
  data: [
    ['A1', 'B1', 'C1', 'D1', 'E1'],
    ['A2', 'B2', 'C2', 'D2', 'E2'],
    ['A3', 'B3', 'C3', 'D3', 'E3'],
    ['A4', 'B4', 'C4', 'D4', 'E4'],
    ['A5', 'B5', 'C5', 'D5', 'E5'],
  ],

Depending on your needs, you can apply configuration options to different elements of your grid:

activeHeaderClassName

Source code

options.activeHeaderClassName : string

currentRowClassName
currentColClassName
currentHeaderClassName
invalidCellClassName
readOnlyCellClassName
commentedCellClassName
noWordWrapClassName
TableClassName
className

Default: "ht__active_highlight"
Category: Core
Since: 0.38.2

allowEmpty

Source code

options.allowEmpty : boolean

The allowEmpty option determines whether Handsontable accepts the following values:

null
undefined
''

You can set the allowEmpty option to one of the following:

Setting	Description
`true` (default)	- Accept `null`, `undefined` and `''` values - Mark cells that contain `null`, `undefined` or `''` values as `valid`
`false`	- Don't accept `null`, `undefined` and `''` values - Mark cells that contain `null`, `undefined` or `''` values with as `invalid`

TIP

To use the allowEmpty option, you need to set the validator option (or the type option).

Default: true
Category: Core
Example

// allow empty values in each cell of the entire grid
allowEmpty: true,

// or
columns: [
  {
    type: 'date',
    dateFormat: 'DD/MM/YYYY',
    // allow empty values in each cell of the 'date' column
    allowEmpty: true
  }

`true`	The `source` data is treated as HTML

Warning: Setting the allowHtml option to true can cause serious XSS vulnerabilities.

Default: false
Category: Core
Example

columns: [
  {
  // set the `type` of each cell in this column to `autocomplete`
  type: 'autocomplete',
  // set options available in every `autocomplete` cell of this column
  source: ['<strong>foo</strong>', '<strong>bar</strong>']
  // use HTML in the `source` list
  allowHtml: true,
  },
],

allowInsertColumn

The cells option overwrites all other options (including options set by columns and cell). It takes the following parameters:

Parameter	Required	Type	Description
`row`	Yes	Number	A physical row index
`column`	Yes	Number	A physical column index
`prop`	No	String \| Number	If `data` is set to an array of arrays, `prop` is the same number as `column`. If `data` is set to an array of objects, `prop` is a property name for the column's data object.

    type: 'checkbox',
  },
  {
    // set the `type` of each cell in this column to `checkbox`
    type: 'checkbox',
    // when checked, the cell's value is `'Yes'`
    checkedTemplate: 'Yes',
    // when unchecked, the cell's value is `'No'`
    uncheckedTemplate: 'No'

TIP

Don't change the className metadata of the column summary row. To style the summary row, use the class name assigned automatically by the ColumnSummary plugin: columnSummaryResult.

To apply different CSS class names on different levels, use Handsontable's cascading configuration.

}

columnSummary

Source code

options.columnSummary : Array<object> | function

    readOnly: true,
    roundFloat: false,
    customFunction(endpoint) {
       return 100;
    }
  }
],

colWidths

Source code

The colWidths option sets columns' widths, in pixels.

The default column width is 50px. To change it, set the colWidths option to one of the following:

Setting	Description	Example
A number	Set the same width for every column	`colWidths: 100`
A string	Set the same width for every column	`colWidths: '100px'`
An array	Set widths separately for each column	`colWidths: [100, 120, undefined]`
A function	Set column widths dynamically, on each render	`colWidths(visualColumnIndex) { return visualColumnIndex * 10; }`
`undefined`	Used by the modifyColWidth hook, to detect column width changes.	`colWidths: undefined`

Setting colWidths even for a single column disables the AutoColumnSize plugin for all columns. For this reason, if you use colWidths, we recommend you set a width for each one of your columns. Otherwise, every column with an undefined width defaults back to 50px, which may cut longer columns names.

Default: undefined
Category: Core
Example

// set every column's width to 100px
colWidths: 100,

// set every column's width to 100px
colWidths: '100px',

// set the first (by visual index) column's width to 100
// set the second (by visual index) column's width to 120
// set the third (by visual index) column's width to `undefined`, so that it defaults to 50px
// set any other column's width to the default 50px (note that longer cell values and column names can get cut)
colWidths: [100, 120, undefined],

// set each column's width individually, using a function
colWidths(visualColumnIndex) {
  return visualColumnIndex * 10;
},

data

Source code

options.data : Array<Array> | Array<object>

The data option sets the initial data of your Handsontable instance.

You can set the data option:

Either to an array of arrays.
Or to an array of objects.

If you don't set the data option (or set it to null), Handsontable renders as an empty 5x5 grid by default.

Example

// as an array of arrays
data: [
  ['A', 'B', 'C'],
  ['D', 'E', 'F'],
