easyui datagrid footer的问题

遇到一个很奇怪的问题，关于datagrid的footer。怎么检查都感觉json没有错误，也设置了showFooter:true,但页面没有出现footer行，分页控件也失效了。设置showFooter:false分页能用，或者将json里的footer:[..里面清空..]，也没有问题，但footer肯定是没有的，请大家帮帮忙。

$(document).ready(function() {

			$('#tt').datagrid({

			    pagination:true,//分页控件  

			    nowrap: true,

					fit: true,

				striped: true,

				rownumbers:true,

				pageSize:20,

				collapsible:true,

				fitColumns : true,

				method : 'POST',

                                showFooter:true,

				singleSelect : true,

				loadMsg:'数据装载中......',

				sortName: 'b6',

				sortOrder: 'asc',

				remoteSort: true,

				idField:'questionsId',

			});



		});

easyui datagrid JavaScript --------------------编程问答-------------------- 分页就只会传2个参数，一个是 total 一个是 rows 。
你把footer 去掉先试试看。 --------------------编程问答--------------------

去掉当然是没问题的，加footer是为了让datagrid有footer行，也就是下面固定一行 --------------------编程问答-------------------- 看下是不是你的高度问题呢。http://www.jeasyui.com/forum/index.php?topic=362.0 --------------------编程问答-------------------- rownumbers:true; --------------------编程问答--------------------

里面就没有高度设置，因为fit:true，是自动吸附的。rownumber:true有什么问题？
