通过poi导出复杂excel既有合并行又有合并列

通过poi导出形如以下的复杂excel：

此excel里左边和右边的用户可以自由选择是否导出这几列，中间的题型有单选、多选、填空、排序

这是详情表，还有分值表如下：

占比表如下：

我自己写了个针对上面的工具类：

还有两个需要用到的dto：

import lombok.Builder;
import lombok.Data;import java.util.List;@Data
@Builder
public class CellModel {// 列对应的keyString colsKey;// 列对应的名字String cellName;// 列所在的起始位置int columIndex;// 列合并数 大于1代表合并int colspan;// 行合并数据，大于代表合并int rowspan;// 列合并数据  比如  A。满意， B.不满意List<String> childCellList;//列合并数据简写  如 A ,BList<String> childQz;String tiltleType;
}

还有：

import lombok.Data;@Data
public class CellValueModel {// 存放keyprivate  String   colsKey;// 存放值private  String   colsValue;
}

还有：

import lombok.Builder;
import lombok.Data;@Data
@Builder
public class RowDataModel {private String id;private String items;private String userName;private String phone;private String email;private String province;private String city;private String country;private String address;private String answer;private String sourceTool;private String sourceWay;private String isLucky;
}

还有：

import lombok.Builder;
import lombok.Data;@Builder
@Data
public class TitleAnswerModel {private String aswerId;private String titleQid;//1private String theAnswer;//Aprivate String theAnswerName;//是private String allowNull;//Nprivate String maxLength;
}

具体的xml文件的sql就不贴了，涉及到公司的代码，以上就是我写的复杂报表的导出功能。
