    ['', 'Email', 'Password'],
    ['User 1', '', ''],
    ['User 2', '', ''],
    ['User 3', '', '']
  ],
  columns: [
    {},
    {
      validator: (value, callback) => {
        callback(/^[^\s@]+@[^\s@]+\.[^\s@]+$/.test(value));
      }
    },
    {
      validator: (value, callback) => {
        callback(value.length >= 8);
      }
    }
