Description 触发场景描述
1、使用List作为数据源，加上模板(e.g.{.name})进行数据写入时，如果list中其中一个map的数据有不存在的key，那一列的数据会上移。
触发Bug的代码
1、map的Test用例
import cn .hutool .core .io .FileUtil ;
import cn .hutool .core .io .resource .ClassPathResource ;
import cn .hutool .core .map .MapUtil ;
import com .alibaba .excel .EasyExcel ;
import com .alibaba .excel .ExcelWriter ;
import com .alibaba .excel .enums .WriteDirectionEnum ;
import com .alibaba .excel .support .ExcelTypeEnum ;
import com .alibaba .excel .write .metadata .WriteSheet ;
import com .alibaba .excel .write .metadata .fill .FillConfig ;
import org .slf4j .Logger ;
import org .slf4j .LoggerFactory ;
import java .io .File ;
import java .util .ArrayList ;
import java .util .List ;
import java .util .Map ;
public class TestMap {
private static final Logger log = LoggerFactory .getLogger (TestMap .class );
public static void main (String [] args ) {
File targetDir ;
if (args .length > 0 && FileUtil .exist (args [0 ])) {
targetDir = FileUtil .file (args [0 ]);
} else {
targetDir = FileUtil .file ("" );
}
File targetFile = new File (targetDir , "targetMap.xlsx" );
if (FileUtil .exist (targetFile )) {
FileUtil .del (targetFile );
}
FileUtil .touch (targetFile );
List <Map <String , String >> list = new ArrayList <>();
list .add (MapUtil .builder ("name" , "张三" ).put ("score" , "99" ).build ());
list .add (MapUtil .builder ("name" , "张四" )/*.put("score", "98")*/ .build ());
list .add (MapUtil .builder ("name" , "张五" ).put ("score" , "97" ).build ());
ExcelWriter writer = EasyExcel .write (targetFile )
.excelType (ExcelTypeEnum .XLSX )
.autoCloseStream (true )
.withTemplate (new ClassPathResource ("classpath://test.xlsx" ).getStream ())
.build ();
WriteSheet writeSheet = EasyExcel .writerSheet (0 , "Sheet1" )
.build ();
FillConfig fillConfig = FillConfig .builder ()
.direction (WriteDirectionEnum .VERTICAL )
.autoStyle (true )
.build ();
writer .fill (list , fillConfig , writeSheet );
writer .finish ();
log .info ("文件输出至：{}" , targetFile .getAbsolutePath ());
}
} 2、VO的测试用例：
import cn .hutool .core .io .FileUtil ;

import com .alibaba .excel .write .metadata .fill .FillConfig ;
import org .slf4j .Logger ;
import org .slf4j .LoggerFactory ;
import java .io .File ;
import java .util .ArrayList ;
import java .util .List ;
import java .util .Map ;
public class TestVO {
private static final Logger log = LoggerFactory .getLogger (TestVO .class );
public static void main (String [] args ) {
File targetDir ;
if (args .length > 0 && FileUtil .exist (args [0 ])) {
targetDir = FileUtil .file (args [0 ]);
} else {
targetDir = FileUtil .file ("" );
}
File targetFile = new File (targetDir , "targetVO.xlsx" );
if (FileUtil .exist (targetFile )) {
FileUtil .del (targetFile );
}
FileUtil .touch (targetFile );
List <SupVO > list = new ArrayList <>();
list .add (new SonVO ("张三" , "99" ));
list .add (new SupVO ("张四" ));
list .add (new SonVO ("张五" , "97" ));
ExcelWriter writer = EasyExcel .write (targetFile )
.excelType (ExcelTypeEnum .XLSX )
.autoCloseStream (true )
.withTemplate (new ClassPathResource ("classpath://test.xlsx" ).getStream ())
.build ();
WriteSheet writeSheet = EasyExcel .writerSheet (0 , "Sheet1" )
.build ();
FillConfig fillConfig = FillConfig .builder ()
.direction (WriteDirectionEnum .VERTICAL )
.autoStyle (true )
.build ();
writer .fill (list , fillConfig , writeSheet );
writer .finish ();
log .info ("文件输出至：{}" , targetFile .getAbsolutePath ());
}
}提示的异常或者没有达到的效果

触发场景描述
1、使用List作为数据源，加上模板(e.g.{.name})进行数据写入时，如果list中其中一个map的数据有不存在的key，那一列的数据会上移。
2、后来经过试验发现，使用继承的VO，当传入的是父类时，对于缺少的属性也会有类似的情况。
