jqgrid 中的动态列名问题得到没有列名和数据的空白网格？在 jqgrid 中获取平淡无奇的网格 nocolumn 名称和日期这是我的代码我无法找到为什么我得到空白网格我正在使用 loadcoplete 事件和 ajax 调用

在此先感谢这是我的代码

<script type="text/javascript">

var jq = jQuery.noConflict();
    jq(function() {
        jq("#grid").jqGrid({

              '','','','','',

              '','','','','',
              '','','','',''],
    colModel:[
