dataTables中的列排序问题

Question

我正在使用dataTables Jquery插件以及twitter引导程序。 我将HTML格式的td内容添加到当数据不在特定范围内时添加弹出框。（具有弹出框的橙色彩色单元格）

现在的问题是，当我对温度列进行排序时，它没有正确排序。请注意，我已经按降序对AS2000的温度进行了排序，但仅对正常单元格进行了排序。

我已经像这样初始化了dataTable

$('#summaryTable').dataTable({
     "aoColumns":[null,null,{"sType": "num-html"},{"sType": "num-html"}]
});  

正常的td单元格包含以下代码

 <td name="temperature_celsius" class="normal sorting_1"><div><span>23.40</span></div> </td>

橙色背景色的单元格包含以下代码

 <td name="temperature_celsius" class="warning sorting_1"> <div> <span data-container="body" data-trigger="hover" data-toggle="popover" data-placement="bottom" data-title="<strong>Alert</strong>" data-html="true" data-content="<p class='text-danger'>Exceeds range limit 30.0 - 20.0 </p>" data-original-title="" title="">61.0</span><i class="icon icon-exclamation-sign pull-right" style="font-size: 21px;"></i></div></td>

有帮助吗？

这里除了日期以外的每个键都是一个device.device键包含以下信息的数组

   [Temperature,Humidity,IsTemperatureRangeExceeds,IsHumidityRangeExceeds,TemperatureRangeLimit,HumidityRangeLimit]

我以以下方式构造表

    $.ajax({  
     type : "POST",   
     url : "http://localhost:8080/tablereports", 
     data: {svalue:JSON.stringify(options)} ,  
     success : function(result) { 

                    obj = JSON.parse(result);             
                    $("#reporttabletbodytempsum").empty();

                    var tablebody = $('#reporttabletbodytempsum');
                    $.each( obj, function( index, value ) { 


                            var convertedDate=value.Date;
                            $.each(value,function(index1,value1){
                               if(index1!="Date"){
//Measurement Type choosen already by the user.it may be Temperature or TemperatureHumidity

                                   if(measurementType =='Temp'){                                                       
                                       if(value1[2]=='true'){

                               }        
                            });            
            tablebody.append($('<tr class="reporttable"><td>'+ ++sno +'</td><td>'+convertedDate+'</td>'+sreialloop+'</tr>'));   



 });
$('[data-toggle="popover"]').popover({
    'placement': 'auto',
    trigger: 'hover'
});       

sumTable = $('#summaryTable').dataTable();              

     },   
     error: function(XMLHttpRequest, textStatus, errorThrown) { 
         alert("Status: " + textStatus); alert("Error: " + errorThrown); 
     }      
    }) ;

有什么更好的办法吗？ 这样我就可以进行排序而没有任何错误。

谢谢Mithun

您应该使用mRender函数设置输出样式。

它将仅修改单元格的显示，但保留基础数据不变，因此可用于排序和过滤。

    "aoColumns": [null, null, {
      mRender: function(data, type, full) {
        if (data >= 5) {
          return '<div name="temperature_celsius" class="warning sorting_1">' + data + '</div>';
        }
        return '-';
      }
    }, {
      mRender: function(data, type, full) {
        if (data >= 20 && data <= 60) {
          return '<div name="temperature_celsius">' + data + '</div>';
        }
        if (data >= 60) {
          return '<div name="temperature_celsius" class="warning sorting_1">' + data + '</div>';
        }
        return '-';
      }
    }]

我将返回的div的样式留给您。

这是一个具有自定义渲染和完整排序功能的Plunker 。
