extjs结合lodop做打印的问题

[ahljxwy]

大家好，我前台用的是EXTJS,现在想用LODOP实现打印功能，extjs的grid数据传给lodop是乱的，有哪位高人做过？指点一下吧，谢谢！

在 JS 中调用控件前用如下方式获得对象

var LODOP=getLodop(document.getElementByIdx_x_x('LODOP_OB'),document.getElementByIdx_x_x('LODOP_EM'));

简单的使用实例

<script language="javascript" type="text/javascript">  
Ext.onReady(function(){
    var win;
 var LODOP; 
    if(!win){
            win = new Ext.Window({
                title:'LODOP打印控件测试',
               
                width:600,
                height:450,
                closeAction:'close',
                plain: true,
    autoLoad:{url:'a.asp',scripts:true},
              
                buttons: [{
                    text:"测试",
     handler: CheckIsInstall
                },
    {
       text:'打印预览',
       handler: prn1_preview
    },{
                    text: 'Close',
                    handler: function(){
                        win.close();
                    }
                }]
            });
        }
        win.show(this); 
  
  function prn1_preview() { 
    CreateOneFormPage(); 
    LODOP.PREVIEW(); 
  };
  function CreateOneFormPage()
  {
   LODOP=getLodop(document.getElementByIdx_x('LODOP_OB'),document.getElementByIdx_x('LODOP_EM')); 
   LODOP.PRINT_INIT("打印控件功能演示_Lodop功能_表单一");
   LODOP.SET_PRINT_STYLE("FontSize",18);
   LODOP.SET_PRINT_STYLE("Bold",1);
   
   LODOP.ADD_PRINT_HTM(18,20,350,600,document.getElementByIdx_x("form2").innerHTML);
  };
  
  
  function CheckIsInstall()
  { 
  try{
       var LODOP=getLodop(document.getElementByIdx_x('LODOP_OB'),document.getElementByIdx_x('LODOP_EM'));
   if ((LODOP!=null)&&(typeof(LODOP.VERSION)!="undefined"))
    Ext.MessageBox.alert("提示","本机已成功安装过Lodop控件!\n  版本号:"+LODOP.VERSION);
    }catch(err)
    {
    //alert("Error:本机未安装或需要升级!");
     }
  }
 }
 )

</script>

LodopFuncs.js 代码

function getLodop(oOBJECT, oEMBED) {
 
 ///

document.getElementByIdx_x("grid").innerHTML 得到的grid里的数据排列是列的啊,grid是extjs的grid
