ExtJs TabPanel装载2个FormPanel后,第二个FormPanel显示不全

Question

TabPanel配置代码如下:

 var centerTabelPanelFifthRpt = new Ext.TabPanel({
region : 'center',
width : '98%',
height : '90%',
title : '人员班别维护',
autoScroll : true,
activeTab : 1,
items : [
centerTabelPanelFifthRpt001,
centerTabelPanelFifthRpt002

]
});

其中一个FormPanel配置如下:

 var centerTabelPanelFifthRpt001 = new Ext.FormPanel({
    region : 'center',
    width : '98%',
    height : '90%',
    title : '员工班别设定',
    activeTab : 0,
    layout : 'column',
    tbar : [ grid_PaiBan ],
    items : [ grid_PaiBan ]
}
});

实际2个FormPanel效果图:

,求怎样才能使2者相同
