如何在jquery datatable中获取多个复选框选中的值

<table id="myTable">
  <thead>
    <tr>
      <th></th>
      <th>Name</th>
      <th>Email</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td><input type="checkbox" value="1"></td>
      <td>John Doe</td>
      <td>john@example.com</td>
    </tr>
    <tr>
      <td><input type="checkbox" value="2"></td>
      <td>Jane Smith</td>
      <td>jane@example.com</td>
    </tr>
    <tr>
      <td><input type="checkbox" value="3"></td>
      <td>Bob Johnson</td>
      <td>bob@example.com</td>
    </tr>
  </tbody>
</table>

$(document).ready(function() {
  $('#myTable').DataTable({
    columnDefs: [{
      orderable: false,
      className: 'select-checkbox',
      targets: 0
    }],
    select: {
      style: 'multi',
      selector: 'td:first-child'
    },
    order: [[1, 'asc']]
  });
});

<button id="getSelectedValues">Get Selected Values</button>

$(document).on('click', '#getSelectedValues', function() {
  var selectedValues = [];
  $('#myTable').DataTable().rows({ selected: true }).every(function() {
    selectedValues.push(this.data()[0]);
  });
  console.log(selectedValues);
});
