jqgrid实现字段显示或隐藏问题

jQuery(grid_selector).jqGrid({
//direction: "rtl",			//表格中文字的显示方向，从左向右（ltr）或者从右向左（rtr）

data: grid_data,
datatype: "local",			//从服务器端返回的数据类型
height: 400,				//表格高度，可以是数字，像素值或者百分比
/****列显示名称******/
colNames:[' ', '', 'id', '订单号', '捆包号', '品名', '规格', '产品牌号(材质)', '数量', '重量(吨)', '质保书编号', '物资来源', '贸易商名称', '物资状态', '合同读取时间', '大宗物资网合同号', '集团合同库合同号', '查看附件', '详情'],
/****常用到的属性：name 列显示的名称；index 传到服务器端用来排序用的列名称；width 列宽度；align 对齐方式；sortable 是否可以排序******/
