Question

我正在使用数据表并初始化如下：

function getDataTableGroupCompany() {

if (dataTableGroupCompany == null) {

     dataTableGroupCompany = $('#dataTables-companyGroupFilter').DataTable({
         'sDom' : 'tp',
         "bDeferRender": true,
         "aoColumns": [
                       {"sClass": "col1" },
                       {"sClass": "col2-current" },
                       null,
                       null,
                       {"sClass": "Just" }
                     ],
                     "iDisplayLength" : 20
                     /* "fnCreatedRow" : function(nRow, aData, iDataIndex) 
                     {
                       var s = $('td:eq(3)', nRow).text();
                       try
                       {
                           $('td:eq(4)', nRow).text(mapCompany[s]);
                       }
                       catch(err)
                       {
                           alert("Y");
                           $('td:eq(4)', nRow).text("0");
                       }

                    } */
        });

     //dataTableGroupCompany.rowGrouping({bExpandableGrouping: true,iGroupingColumnIndex:3,iGroupingOrderByColumnIndex:4, sGroupingColumnSortDirection: "desc",bHideGroupingOrderByColumn:false,fnGroupLabelFormat:function(label){ if(mapCompany[label]!=null) return label+" ("+mapCompany[label]+")"; else return label; }});
     dataTableGroupCompany.rowGrouping({bExpandableGrouping: true,iGroupingColumnIndex:3,iGroupingOrderByColumnIndex:4, sGroupingColumnSortDirection: "desc",fnGroupLabelFormat:function(label){ if(mapCompany[label]!=null) return label+" ("+mapCompany[label]+")"; else return label; }});
}

return dataTableGroupCompany;    
}

 // ...//
 dataTableGroupCompany = getDataTableGroupCompany();

现在，当我尝试使用sortToggle函数再次对表进行排序时

 function sortToggle()
 {
var SortButton = $('#sortButton');

if(sort==true)
    {
    sort=false;

   //1st Exception in This line

    dataTableGroupCompany.rowGrouping({bExpandableGrouping: true,iGroupingColumnIndex:3,iGroupingOrderByColumnIndex:4, sGroupingColumnSortDirection: "desc",fnGroupLabelFormat:function(label){ if(mapCompany[label]!=null) return label+" ("+mapCompany[label]+")"; else return label; }});

   //
    dataTableGroupCompany.fnDraw();
    dataTableGroupIndustry.rowGrouping({bExpandableGrouping: true,iGroupingColumnIndex:3,iGroupingOrderByColumnIndex:4, sGroupingColumnSortDirection: "desc",fnGroupLabelFormat:function(label){ if(mapIndustry[label]!=null) return label+" ("+mapIndustry[label]+")"; else return label; }});
    dataTableGroupIndustry.fnDraw();
    dataTableGroupPeople.rowGrouping({bExpandableGrouping: true,iGroupingColumnIndex:3,iGroupingOrderByColumnIndex:4, sGroupingColumnSortDirection: "desc",fnGroupLabelFormat:function(label){ if(mapPlace[label]!=null) return label+" ("+mapPlace[label]+")"; else return label; }});
    dataTableGroupPeople.fnDraw();
    $("#sortButton").html('ASC');
    }
else
    {
    sort=true;

    dataTableGroupCompany.rowGrouping({bExpandableGrouping: true,iGroupingColumnIndex:3,iGroupingOrderByColumnIndex:4, sGroupingColumnSortDirection: "asc",fnGroupLabelFormat:function(label){ if(mapCompany[label]!=null) return label+" ("+mapCompany[label]+")"; else return label; }});
    dataTableGroupCompany.fnDraw();

    dataTableGroupIndustry.rowGrouping({bExpandableGrouping: true,iGroupingColumnIndex:3,iGroupingOrderByColumnIndex:4, sGroupingColumnSortDirection: "asc",fnGroupLabelFormat:function(label){ if(mapIndustry[label]!=null) return label+" ("+mapIndustry[label]+")"; else return label; }});
    dataTableGroupIndustry.fnDraw();

    dataTableGroupPeople.rowGrouping({bExpandableGrouping: true,iGroupingColumnIndex:3,iGroupingOrderByColumnIndex:4, sGroupingColumnSortDirection: "asc",fnGroupLabelFormat:function(label){ if(mapPlace[label]!=null) return label+" ("+mapPlace[label]+")"; else return label; }});
    dataTableGroupPeople.fnDraw();

    $("#sortButton").html('DESC');
    }

}

它在所有rowGrouping行中给出错误，就像我在评论中显示的第一个异常一样。我不知道为什么会这样。错误就像，

未捕获的TypeError：无法读取属性＆＃39; _aData＆＃39; of undefinedjquery.dataTables.js：774 _fnGetCellDatajquery.dataTables.js：5712 fnGetDatajquery.dataTables.rowGrouping.js：415 _fnDrawCallBackWithGroupingjquery.dataTables.js：4851 _fnCallbackFirejquery.dataTables.js：1566 _fnDrawjquery.dataTables.js：2184 _fnFilterCompletejquery.dataTables.js ：4099 _fnSortjquery.dataTables.js：1594 _fnReDrawjquery.dataTables.js：5558 fnDrawjquery.dataTables.rowGrouping.js：684（匿名函数）jquery.min.js：2 p.extend.eachjquery.min.js：2 p.fn .p.eachjquery.dataTables.rowGrouping.js：114 $ .fn.rowGroupingpeople.html：1315 sortTogglepeople.html：1568 onclick

数据行分组抛出异常
