解决方案

使用下面的代码：

$('body').tooltip({
   selector: 'td.details-control',
   title: 'Click to expand',
   container: 'body',
   placement: 'right'
});

/* Formatting function for row details - modify as you need */
function format ( d ) {
    // `d` is the original data object for the row
    return '<table cellpadding="5" cellspacing="0" border="0" style="padding-left:50px;">'+
        '<tr>'+
            '<td>Full name:</td>'+
            '<td>'+d.name+'</td>'+
        '</tr>'+
        '<tr>'+
            '<td>Extension number:</td>'+
            '<td>'+d.extn+'</td>'+
        '</tr>'+
    '</table>';
}
 
$(document).ready(function() {
  
  $('body').tooltip({
    selector: 'td.details-control',
    title: 'Click to expand',
    container: 'body',
    placement: 'right'
  });  
  
    var data = [{"name":"Tiger Nixon","position":"System Architect","salary":"$320,800","start_date":"2011/04/25","office":"Edinburgh","extn":"5421"},{"name":"Garrett Winters","position":"Accountant","salary":"$170,750","start_date":"2011/07/25","office":"Tokyo","extn":"8422"},{"name":"Ashton Cox","position":"Junior Technical Author","salary":"$86,000","start_date":"2009/01/12","office":"San Francisco","extn":"1562"}];
