在easyui中初始化  加载加datagrid就好了。如下，

<script>
$(function(){
	initDatagrid(); //初始化四种形态
	initDatagrid2();//已提交保送信息
	window.setTimeout(function(){
		loadDatagrid(); 			//加载待确认
	},100);//延迟100毫秒执行，避免请求提交两次的问题
	$(".datagrid-body").css("overflow-x","hidden");//显示横向滚动条
});
</script>

//init
function initDatagrid(){
	//表格
	 var columnArr =[
		{field:'ck',title:'选择',width:5,halign:'center',align:'center',
			editor:{
				type:'validatebox',
		        options:{required:true,validType:"length[1,20]",editable:false  }
			},
			formatter : function(value,row,index){
		    return '<input type="radio" onclick="sel('+row.f4NotifiedId+')" name="f4NotifiedId" value="'+row.f4NotifiedId+'" />';
			}
		}, 
		{field:'workYear',title:'年',width:10,halign:'center',
			editor:{
				type:'validatebox',
				options:{required:true,validType:"length[1,100]"}
			}
		},
		{field:'reason',title:'季度',width:10,halign:'center',
			editor:{
				type:'validatebox',
				options:{required:true,validType:"length[1,100]"}
			}
		},
		{field:'createUser',title:'创建者',width:10,halign:'center',
			editor:{
				type:'validatebox',
				options:{required:true,validType:"length[1,100]"}
			}
		},
		{field:'templateFileName',title:'模板名称',width:10,halign:'center',
			editor:{
				type:'validatebox',
				options:{required:true,validType:"length[1,100]"}
			}
		},
		{field:'createTime',title:'创建时间',width:10,halign:'center', 
			editor:{
				type:'validatebox',
				options:{required:true,validType:"length[1,100]"}
			},
			formatter: function(value,row,index){
				if(!value){
					return "";
				}
		        var dateValue = new Date(value);
		        return dateFormat(dateValue, dateFormat.masks.isoDate);
	    	}
		},
		{field:'endDate',title:'反馈截止时间',width:10,halign:'center',
			editor:{
				type:'validatebox',
				options:{required:true,validType:"length[1,100]"}
			}
		},
		{field:'status',title:'下发状态',width:10,halign:'center',
			editor:{
				type:'validatebox',
				options:{required:true,validType:"length[1,100]"}
			},
	     	formatter : function(value,row,index){
	     		 if(value=='0'){
	            	  return '<span style="color:green">未下发</span>'
	              }else if(value == '1'){
	            	  return '已下发';
	              }else if(value == '2'){
	            	  return '已结束';
	              }
	        }
		},
		{field:'_operate',title:'操作',width:20,halign:'center',
			editor:{
				type:'validatebox',
				options:{required:true,validType:"length[1,100]"}
			},
			formatter: function(value,row,index){
				var $tHtml = '';
				$tHtml = $tHtml + '<input type="button" class="" name="button1" onclick="send('+row.f4NotifiedId+');" value="下发"/>';
				$tHtml = $tHtml + '<input type="button" class="" name="button1" onclick="update('+row.f4NotifiedId+');" value="修改"/>';
				$tHtml = $tHtml + '<input type="button" class="" name="button1" onclick="del('+row.f4NotifiedId+');" value="删除"/>';
				return $tHtml;
	        }
		}
	];
	 
	 $('#dataTable').datagrid({
		   fitColumns : true,	//列适应表格宽度
		    striped : true,	//设置为true将交替显示行背景。
		    nowrap : false,	//设置为true，当数据长度超出列宽时将会自动截取
		    rownumbers : true,
		    singleSelect : true,
		    selectOnCheck : false,
		    checkOnSelect:false,
		    pagination : true,	//添加分页栏
			pageSize : 10,	//每页显示多少条?
			pageList : [5,10,20,30,50],
			sortOrder : 'desc',
			idField:'id',
			scrollbarSize :0,
			columns:[columnArr]
	});
}

//load
function loadDatagrid(){
	var queryParams={};
	// ---- table load
    var options = $('#dataTable').datagrid('options');
    options.url = '${pageContext.request.contextPath}/s/manage/f4/****/list';
    options.queryParams = queryParams;
    $('#dataTable').datagrid(options);
}

在下面方法中，

//load
function loadDatagrid(){
	var queryParams={};
    var options = $('#dataTable').datagrid('options');
    options.url = '${pageContext.request.contextPath}/s/manage/f4/****/list';
    options.queryParams = queryParams;
    $('#dataTable').datagrid(options);
}

控制台提示的   var options = $('#dataTable').datagrid('options'); 这一行有问题。查询代码发现在就绪函数中我没有初始化initDatagrid2()，所以提示的没有定义。加上就好了，记录一下
