# 场景
在报表服务插件的GetReportHeaders方法里创建的列，设置列宽无效
# 原因
报表的过滤框的显示隐藏列的字段有默认宽度，这个优先级较高
# 解决方法
编写过滤框的表单插件，修改显示隐藏列字段的默认宽度
```language
using Kingdee.BOS.Core.CommonFilter;
using Kingdee.BOS.Core.CommonFilter.PlugIn;

base.AfterBindData(e);
//获取隐藏列字段
ICommonFilterModelService filterModel = this.Model as ICommonFilterModelService;
if (filterModel == null)
return;
var fieldList = filterModel.ColumnObject.AllFieldList;
//遍历字段设置列宽
foreach (var item in fieldList)
{
//标题包含 '日期'
if (item.Caption.ToString().Contains("日期"))
{
//默认列宽
item.DefaultColWidth = 160;
