javascript - 如何更改数据表中按钮的位置

Question

我有以下代码:

var dataSet = [
  ["Airi Satou", "Accountant", "Tokyo", "5407", "2008/11/28", "$162,700"],
  ["Angelica Ramos", "Chief Executive Officer (CEO)", "London", "5797", "2009/10/09", "$1,200,000"],
  ["Gavin Joyce", "Developer", "Edinburgh", "8822", "2010/12/22", "$92,575"],
  ["Jennifer Chang", "Regional Director", "Singapore", "9239", "2010/11/14", "$357,650"],
  ["Brenden Wagner", "Software Engineer", "San Francisco", "1314", "2011/06/07", "$206,850"],
  ["Fiona Green", "Chief Operating Officer (COO)", "San Francisco", "2947", "2010/03/11", "$850,000"],
  ["Shou Itou", "Regional Marketing", "Tokyo", "8899", "2011/08/14", "$163,000"],
  ["Martena Mccray", "Post-Sales support", "Edinburgh", "8240", "2011/03/09", "$324,050"],
  ["Unity Butler", "Marketing Designer", "San Francisco", "5384", "2009/12/09", "$85,675"]
];

$(document).ready(function() {
  $('#example').DataTable({
    dom: 'Blfrtip',
    data: dataSet,
    buttons: ['copy', 'excel'],
    columns: [{
      title: "Name"
    }, {
      title: "Position"
    }, {
      title: "Office"
    }, {
      title: "Extn."
    }, {
      title: "Start date"
    }, {
      title: "Salary"
    }]
  });
});

<table id="example" class="display" width="100%">
<tfoot><tr></tr></tfoot>
</table>

我想要做的是将按钮位置更改为中心，如下所示:

如何实现？

SOLUTION

您可以使用以下 CSS 规则。请注意，它将针对页面上的所有表格。使用更具体的规则仅针对一个表。

.dataTables_wrapper .dt-buttons {
  float:none;  
  text-align:center;
}

此外，为了使其正常工作，您需要使用 dom: 'lfBrtip'。参见 dom选项了解更多详情。
