Add a table tag, 92cee25da80fac49f6fb6eec5fd2c22ae067cb307e7ced06402413ceff3b500b You can not use it, you can dynamically load

<table id="sample-table-2" class="table table-striped table-bordered table-hover"> 
    <thead> 
      <tr> 
        <th class="center"><label> 
            <input type="checkbox" class="ace" /> 
            <span class="lbl"></span> 
          </label> 
        </th> 
        <th>名称</th> 
        <th>apiKey</th> 
        <th>secretKey</th> 
        <th><i class="icon-time bigger-110 hidden-480"></i> 创建时间</th> 
        <th class="hidden-480">Status</th> 
        <th>操作</th>

Backend code:

   // 获取前端过来的参数,下面三个参数是 dataTable默认的，不要随便更改 
    Integer sEcho = Integer.valueOf(params.get("sEcho"));// 记录操作的次数 每次加1 
    Integer iDisplayStart = Integer.valueOf(params.get("iDisplayStart"));// 起始 
    Integer iDisplayLength = Integer.valueOf(params.get("iDisplayLength"));// 每页显示的size 
 
    Map<String, Object> map = new HashMap<String, Object>(); 
    try { 
      // 查询数据,分页的话我这边使用的是 PageHelper，这边不介绍了 
      PagedResult<PushEntity> list = pushEntityService.findByUserId( 
          pushUser.getId(), iDisplayStart, iDisplayLength); 
 
      // 为操作次数加1，必须这样做 
      int initEcho = sEcho + 1;

  //返回参数也是固定的 
      map.put("sEcho", initEcho); 
      map.put("iTotalRecords", list.getTotal());//数据总条数 
      map.put("iTotalDisplayRecords", list.getTotal());//显示的条数 
      map.put("aData", list.getDataList());//数据集合 
    } catch (Exception e) { 
      e.printStackTrace(); 
    } 
 
    return map;
