您可以这样做来创建类似的按钮

$(document).ready(function() {
  var table = $('#example').DataTable({
    dom: 'Bfrtip',
    buttons: [{
        text: '10',
        action: function(e, dt, node, config) {
          table.page.len(10).draw();
        }
      },
      {
        text: '25',
        action: function(e, dt, node, config) {
          table.page.len(25).draw();
        }
      },
      {
        text: '50',
        action: function(e, dt, node, config) {
          table.page.len(50).draw();
        }
      },
      {
        text: '100',
        action: function(e, dt, node, config) {
          table.page.len(100).draw();
        }
      },
      {
        text: 'To dos',
        action: function(e, dt, node, config) {
          //do whatever you want to do
        }
      }
    ]
  });
});

body {
  font: 90%/1.45em "Helvetica Neue", HelveticaNeue, Verdana, Arial, Helvetica, sans-serif;
  margin: 0;
  padding: 0;
  color: #333;
  background-color: #fff;
}
