easyui datagrid 列显示和隐藏

//当查询IT基础设施的时候隐藏'STAFF_ID'、'ITSM_STAFF_ID'
    if($("input[name='currentstate']").val()==2){
        $('#ordertable').datagrid('hideColumn','STAFF_ID');
        $('#ordertable').datagrid('hideColumn','ITSM_STAFF_ID');
    }else{
        $('#ordertable').datagrid('showColumn','STAFF_ID');
　　     $('#ordertable').datagrid('showColumn','ITSM_STAFF_ID');

    }
    // 清空选中行
    SERVICEDATAGRID.datagrid('clearSelections');

$('#ordertable').datagrid('hideColumn','列field');//隐藏列
把hideColumn换成showColumn 即为显示列
