Overview

Handsontable utilizes the HTML table structure so customization is based either on referencing to the already existing elements, such as TR/TD, or by applying your own CSS classes to HTML elements.

A cell can be formatted either using a CSS class or with a style applied directly to the DOM element.

Apply custom CSS class styles

In this example, we add a custom class custom-cell to the cell in the top left corner and add a custom-table CSS class that highlights the table headers.

const container = document.querySelector('#example1'); const hot = new Handsontable(container, { data: Handsontable.helper.createSpreadsheetData(5, 5), rowHeaders: true, colHeaders: true, stretchH: 'all', className: 'custom-table', cell: [ { row: 0, col: 0, className: 'custom-cell', }, ], height: 'auto', licenseKey: 'non-commercial-and-evaluation', }); <script src="https://cdn.jsdelivr.net/npm/handsontable@10.0/dist/handsontable.full.min.js"></script> <link type="text/css" rel="stylesheet" href="https://cdn.jsdelivr.net/npm/handsontable@10.0/dist/handsontable.full.min.css" /> <div id="example1" class="hot "></div> td.custom-cell { color: #fff; background-color: #37bc6c; } .custom-table thead th:nth-child(even), .custom-table tbody tr:nth-child(odd) th { background-color: #d7f1e1; }

const container = document.querySelector('#example1');

const hot = new Handsontable(container, {
  data: Handsontable.helper.createSpreadsheetData(5, 5),
  rowHeaders: true,
  colHeaders: true,
  stretchH: 'all',
  className: 'custom-table',
  cell: [
    {
      row: 0,
      col: 0,
      className: 'custom-cell',
    },
  ],
  height: 'auto',
  licenseKey: 'non-commercial-and-evaluation',
});

td.custom-cell {
  color: #fff;
  background-color: #37bc6c;
}
.custom-table thead th:nth-child(even),
.custom-table tbody tr:nth-child(odd) th {
  background-color: #d7f1e1;
}

Apply inline styles

You can apply inline styles directly to the DOM element using its style attribute. You can use the renderer option to do that.

const container = document.querySelector('#example2'); Handsontable .renderers .registerRenderer('customStylesRenderer', (hotInstance, TD, ...rest) => { Handsontable.renderers.getRenderer('text')(hotInstance, TD, ...rest); TD.style.fontWeight = 'bold'; TD.style.color = 'green'; TD.style.background = '#d7f1e1'; }); const hot = new Handsontable(container, { data: Handsontable.helper.createSpreadsheetData(5, 5), rowHeaders: true, colHeaders: true, stretchH: 'all', cell: [ { row: 0, col: 0, renderer: 'customStylesRenderer', }, ], height: 'auto', licenseKey: 'non-commercial-and-evaluation' }); <script src="https://cdn.jsdelivr.net/npm/handsontable@10.0/dist/handsontable.full.min.js"></script> <link type="text/css" rel="stylesheet" href="https://cdn.jsdelivr.net/npm/handsontable@10.0/dist/handsontable.full.min.css" /> <div id="example2" class="hot "></div>

const container = document.querySelector('#example2');

Handsontable
  .renderers
  .registerRenderer('customStylesRenderer', (hotInstance, TD, ...rest) => {
    Handsontable.renderers.getRenderer('text')(hotInstance, TD, ...rest);

    TD.style.fontWeight = 'bold';
    TD.style.color = 'green';
    TD.style.background = '#d7f1e1';
  });

const hot = new Handsontable(container, {
  data: Handsontable.helper.createSpreadsheetData(5, 5),
  rowHeaders: true,
  colHeaders: true,
  stretchH: 'all',
  cell: [
    {
      row: 0,
      col: 0,
      renderer: 'customStylesRenderer',
    },
  ],
  height: 'auto',
  licenseKey: 'non-commercial-and-evaluation'
});

Custom cell borders

To enable the custom borders feature, set the customBorders option. This can either be set as true or initialized as an array with a pre-defined setup.

To initialize Handsontable with predefined custom borders, provide the cell coordinates and border styles in form of an array:

• with row/col pairs: { row: 2, col: 2, left: { /*...*/ } }
• or with range details: { range: { from: { row: 1, col: 1 }, to: { row: 3, col: 4 } }, left: { /*...*/ } }

const container = document.getElementById('example3'); const hot = Handsontable(container, { data: Handsontable.helper.createSpreadsheetData(5, 6), rowHeaders: true, colHeaders: true, stretchH: 'all', height: 'auto', licenseKey: 'non-commercial-and-evaluation', customBorders: [ { range: { from: { row: 1, col: 1 }, to: { row: 3, col: 4 } }, top: { width: 2, color: '#5292F7' }, left: { width: 2, color: 'orange' }, bottom: { width: 2, color: 'red' }, right: { width: 2, color: 'magenta' } }, { row: 2, col: 2, left: { width: 2, color: 'red' }, right: { width: 1, color: 'green' } } ] }); <script src="https://cdn.jsdelivr.net/npm/handsontable@10.0/dist/handsontable.full.min.js"></script> <link type="text/css" rel="stylesheet" href="https://cdn.jsdelivr.net/npm/handsontable@10.0/dist/handsontable.full.min.css" /> <div id="example3" class="hot "></div>

const container = document.getElementById('example3');

const hot = Handsontable(container, {
  data: Handsontable.helper.createSpreadsheetData(5, 6),
  rowHeaders: true,
  colHeaders: true,
  stretchH: 'all',
  height: 'auto',
  licenseKey: 'non-commercial-and-evaluation',
  customBorders: [
    {
      range: {
        from: {
          row: 1,
          col: 1
        },
        to: {
          row: 3,
          col: 4
        }
      },
      top: {
        width: 2,
        color: '#5292F7'
      },
      left: {
        width: 2,
        color: 'orange'
      },
      bottom: {
        width: 2,
        color: 'red'
      },
      right: {
        width: 2,
        color: 'magenta'
      }
    },
    {
      row: 2,
      col: 2,
      left: {
        width: 2,
        color: 'red'
      },
      right: {
        width: 1,
        color: 'green'
      }
    }
  ]
});
