修改bootstraptable默认detailRow样式的实例代码

this.$body.find('> tr[data-index] > td > .detail-icon').off('click').on('click', function () {
  var $this = $(this),  //a.detail-icon
    $tr = $this.parent().parent(),   //current row
    index = $tr.data('index'),
    row = data[index]; // Fix #980 Detail view, when searching, returns wrong row
  // remove and update
  if ($tr.next().is('tr.detail-view')) {   //exsit
    $this.find('i').attr('class', sprintf('%s %s', that.options.iconsPrefix, that.options.icons.detailOpen));
    that.trigger('collapse-row', index, row);
    $tr.next().remove();
    $tr.next().remove();
  } else {    //not exsit and add
    $this.find('i').attr('class', sprintf('%s %s', that.options.iconsPrefix, that.options.icons.detailClose));
    //$tr.after(sprintf('', $tr.find('td').length));
    $tr.after(sprintf(''));
    $tr.after(sprintf(''));
    var $element1 = $tr.next();
    var $element2 = $element1.next();
    //var $
    //var $element = $tr.next().find('td');
    var cOntent= calculateObjectValue(that.options, that.options.detailFormatter, [index, row, $element1, $element2], '');
    //console.log(content);  //head , body Object
    if($element1.length === 1) {
      $element1.append(content.head);
