宽度无法本地缓存

[kavizzz]

问题：我的表头和内容都是动态的，每次进入页面我都会请求表头数据和内容数据，然后给GM赋值，但是宽度无法缓存， 列的顺序可以缓存, 修改了列序和列宽之后， 刷新再次进入页面宽度就还原了， 列序是改变后的， 看localstorage中的宽度是修改后的
GM版本： 3.2.1

表头数据 [{"key":"sn","text":"编号"},{"key":"project_name","text":"项目名称"},{"key":"project_manager","text":"项目经理"},{"key":"company_attr","text":"公司属性"},{"key":"project_type","text":"项目类型"},{"key":"buildings_type","text":"建筑类型"},{"key":"owner_name","text":"甲方名称"},{"key":"project_province","text":"项目省份"},{"key":"contract_code","text":"合同编号"},{"key":"sign_date","text":"签订日期"},{"key":"contract_amount","text":"合同金额"},{"key":"contract_amount_notax","text":"不含税金额"},{"key":"contract_days","text":"工期（天数）"},{"key":"status","text":"审批状态"},{"key":"archive_status","text":"归档状态"},{"key":"created_at","text":"发起时间"},{"key":"created_by","text":"发起人"},{"key":"updated_at","text":"最后修改时间"},{"key":"updated_by","text":"修改人"},{"key":"optGm","text":"操作列","fixed":"right","width":"80px"}]
