finereport介绍的动态分组是默认“地区”必须参加分组，那么如果我希望地区字段也是动态的呢，需要怎么改呢，知道的大佬求解决方案哇SELECT 地区 ${if(len(销售员)=0,"",",销售员")} ${if(len(产品类型)=0,"",",产品类型")} ${if(len(产品)=0,"",",产品")} ,sum(销量) as 销量汇总 FROM 销量where 1=1 ${if(len(销售员)==0,"","and 销售员 in ('" +销售员+ "')")} ${if(len(产品类型)==0,"","and 产品类型 in ('" +产品类型+ "')")} ${if(len(产品)==0,"","and 产品 in ('" +产品+ "')")} group by 地区 ${if(len(销售员)=0,"",",销售员")} ${if(len(产品类型)=0,"",",产品类型")} ${if(len(产品)=0,"",",产品")}
