Overview

The password cell type behaves like a text cell, the only difference being that it masks its value using asterisks in the cell renderer. An <input type="password"> field is used for the cell editor. Data is stored in the data source as plain text.

const container = document.querySelector('#example1'); const hot = new Handsontable(container, { data: [ { id: 1, name: { first: 'Chris', last: 'Right' }, password: 'plainTextPassword' }, { id: 2, name: { first: 'John', last: 'Honest' }, password: 'txt' }, { id: 3, name: { first: 'Greg', last: 'Well' }, password: 'longer' } ], colHeaders: ['ID', 'First name', 'Last name', 'Password'], height: 'auto', licenseKey: 'non-commercial-and-evaluation', columns: [ { data: 'id' }, { data: 'name.first' }, { data: 'name.last' }, { data: 'password', type: 'password' } ] }); <script src="https://cdn.jsdelivr.net/npm/handsontable@12.1/dist/handsontable.full.min.js"></script> <link type="text/css" rel="stylesheet" href="https://cdn.jsdelivr.net/npm/handsontable@12.1/dist/handsontable.full.min.css" /> <div id="example1" class="hot "></div>

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

const hot = new Handsontable(container, {
  data: [
    { id: 1, name: { first: 'Chris', last: 'Right' }, password: 'plainTextPassword' },
    { id: 2, name: { first: 'John', last: 'Honest' }, password: 'txt' },
    { id: 3, name: { first: 'Greg', last: 'Well' }, password: 'longer' }
  ],
  colHeaders: ['ID', 'First name', 'Last name', 'Password'],
  height: 'auto',
  licenseKey: 'non-commercial-and-evaluation',
  columns: [
    { data: 'id' },
    { data: 'name.first' },
    { data: 'name.last' },
    { data: 'password', type: 'password' }
  ]
});

Fixed hash length

By default, every hash has a length equal to the length of its corresponding value. Use option hashLength to set a fixed hash length.

const container = document.querySelector('#example2'); const hot = new Handsontable(container, { data: [ { id: 1, name: { first: 'Chris', last: 'Right' }, password: 'plainTextPassword' }, { id: 2, name: { first: 'John', last: 'Honest' }, password: 'txt' }, { id: 3, name: { first: 'Greg', last: 'Well' }, password: 'longer' } ], colHeaders: ['ID', 'First name', 'Last name', 'Password'], height: 'auto', licenseKey: 'non-commercial-and-evaluation', columns: [ { data: 'id' }, { data: 'name.first' }, { data: 'name.last' }, { data: 'password', type: 'password', hashLength: 10 } ] }); <script src="https://cdn.jsdelivr.net/npm/handsontable@12.1/dist/handsontable.full.min.js"></script> <link type="text/css" rel="stylesheet" href="https://cdn.jsdelivr.net/npm/handsontable@12.1/dist/handsontable.full.min.css" /> <div id="example2" class="hot "></div>

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

const hot = new Handsontable(container, {
  data: [
    { id: 1, name: { first: 'Chris', last: 'Right' }, password: 'plainTextPassword' },
    { id: 2, name: { first: 'John', last: 'Honest' }, password: 'txt' },
    { id: 3, name: { first: 'Greg', last: 'Well' }, password: 'longer' }
  ],
  colHeaders: ['ID', 'First name', 'Last name', 'Password'],
  height: 'auto',
  licenseKey: 'non-commercial-and-evaluation',
  columns: [
    { data: 'id' },
    { data: 'name.first' },
    { data: 'name.last' },
    { data: 'password', type: 'password', hashLength: 10 }
  ]
});

Custom hash symbol

By default, every hash consists of asterisks *. Use the option hashSymbol to set a custom hash symbol. You can use any character, entity, or even HTML. Note that you can't change the symbol used by the input field due to browser limitations.

const container = document.querySelector('#example3'); const hot = new Handsontable(container, { data: [ { id: 1, name: { first: 'Chris', last: 'Right' }, password: 'plainTextPassword' }, { id: 2, name: { first: 'John', last: 'Honest' }, password: 'txt' }, { id: 3, name: { first: 'Greg', last: 'Well' }, password: 'longer' } ], colHeaders: ['ID', 'First name', 'Last name', 'Password'], height: 'auto', licenseKey: 'non-commercial-and-evaluation', columns: [ { data: 'id' }, { data: 'name.first' }, { data: 'name.last' }, { data: 'password', type: 'password', hashSymbol: '■' } ] }); <script src="https://cdn.jsdelivr.net/npm/handsontable@12.1/dist/handsontable.full.min.js"></script> <link type="text/css" rel="stylesheet" href="https://cdn.jsdelivr.net/npm/handsontable@12.1/dist/handsontable.full.min.css" /> <div id="example3" class="hot "></div>

const container = document.querySelector('#example3');

const hot = new Handsontable(container, {
  data: [
    { id: 1, name: { first: 'Chris', last: 'Right' }, password: 'plainTextPassword' },
    { id: 2, name: { first: 'John', last: 'Honest' }, password: 'txt' },
    { id: 3, name: { first: 'Greg', last: 'Well' }, password: 'longer' }
  ],
  colHeaders: ['ID', 'First name', 'Last name', 'Password'],
  height: 'auto',
  licenseKey: 'non-commercial-and-evaluation',
  columns: [
    { data: 'id' },
    { data: 'name.first' },
    { data: 'name.last' },
    { data: 'password', type: 'password', hashSymbol: '■' }
  ]
});
