修改 bootstrap table 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));
