小厂，用的开源birt做报表，不太符合用户对报表的操作习惯。
用户对报表希望：
- 自定义显示、隐藏列；
- 自定义报表列的显示顺序；
- 自定义报表列宽度；
- 按用户选择的列对表格数据排序
- 冻结表头
自定义定义显示列等
解决这类问题，有3种思路，
第一种，是全动态的，根据设置动态生成报表文件。
第二种：在beforefactory等函数当中，动态修改相关对象及其属性
第三种：设置相关函数，绑定在特定的元素上。
我们先采取第2种思路实现。
实现列的排序的做法：关键是通过birt设计句柄,获得明细区单元格及头部区单元格，把特定的单元格移动到指定位置，为简单起见，采取全部列重排方式实现。

importPackage(Packages.org.eclipse.birt.report.model.api.elements.table); //******获取表名
var table1= reportContext.getDesignHandle().findElement("table1");
/************排序明细***************/ var details=table1.getDetail();var detail1=details.getContents().get(0);
//获取明细行的所有单元格
var dcells=detail1.getCells();
//通过前端参数 列出所有明细单元格--获取的是初始位置var dcell1=dcells.get(position1);//position1 是原来的位置decell1.moveTo(pos2); //把cell1 挪动到pos2指定位置......显示、隐藏列，通过报表设计元素获取表格的列对象，代码直接操作列对象的属性即可。
var table1= reportContext.getDesignHandle().findElement("table1");
var cols=table1.getColumns();
cols.get(pos1).setProperty("display", "none");设置报表的宽度：
var dynamicHeight=20+"in"; //don't forget the unit
reportContext.getDesignHandle().findMasterPage("Simple MasterPage").setProperty("width", dynamicHeight);
reportContext.getDesignHandle().findMasterPage("Simple MasterPage").pageType="custom";按特定列对报表数据排序，需要在dataset脚本的beforeOpen中，动态拼接sql

数据库当中必须记录用户设置的列相关参数：

PARASARR VARCHAR2(4000),

-- Add comments to the table
comment on table COLUMNPARAMETER
is '报表列参数表';
-- Add comments to the columns
comment on column COLUMNPARAMETER.REPORTID
is '报表id';
comment on column COLUMNPARAMETER.REPORTURL
is '参数链接';
comment on column COLUMNPARAMETER.PARASARR
is '参数数组字符串';
comment on column COLUMNPARAMETER.ORDERPARAS
is '排序参数';
comment on column COLUMNPARAMETER.CPARASARR
is '大参数数组字符串';
comment on column COLUMNPARAMETER.DEFAULTCPARASARR
is '默认大参数数组字符串';由于我厂参数是配置的：
需要增加几个参数:
columnsManage 指定列的顺序、是否隐藏、列的宽度
关于指定列排序：
我们需要增加二个参数：按哪一列排序、是升序还是降序：
（指定按列排序的表字段）
（指定的列是升序还是降序）
相应的birt报表文件中，dataset对象的beforeopen方法中增加如下代码
if(screen!=""&&screen!=null&&screen!="null"){
if(seach!=""&&seach!=null&&seach!="null"){
this.queryText = "select * from (" + this.queryText +") where "+ seach +" like'%" + screen +"%'" ;
//添加排序参数：
if(col!=null && col!="" &&col!="null"&sort!=null &&sort!="" &&sort!="null"){
this.queryText ="select * from ("+this.queryText+") order by "+col+" "+sort;
}
}
}
这个代码的主要作用是：根据接受的指定的列名、升降序，拼sql，使得执行该sql查询语句后，结果是排序过的。
绑定参数与报表的关系：
参数设置了，报表文件中根据传入的参数进行了处理，还需要把2者关联起来，我厂做了一个报表服务，关联报表及参数间关系：
绑定了参数，还需要指定参数在页面上布局的位置：
设置表头背景图片宽度等的位置：
（设置的位置示意图）
