html code:
                  <table id="dg" class="easyui-datagrid"> 
                   <thead> 
                       <tr> 
                           <th data-options="field:'code'">Code</th> 
                           <th data-options="field:'name'">Name</th>
                       </tr> 
                   </thead> 
         </table>
Jquery code:

             tds+="<tr>";
             tds+="<td>" + code + "</td>";
             tds+="<td>" + name + "</td>";
             tds+="</tr>";
