JavaScript Data Grid Configuration options

JavaScript Data GridConfiguration options

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):

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'],

    ['A4', 'B4', 'C4', 'D4', 'E4'],
    ['A5', 'B5', 'C5', 'D5', 'E5'],

colWidths

Source code

options.colWidths : number | Array<number> | string | Array<string> | Array<undefined> | function

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.

Read more:

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;
},

Handsontable's data is bound to your source data by reference (i.e. when you edit Handsontable's data, your source data alters as well).

You can set the data option:

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