POI setCellStyle 没有效果

Posted

tags:

篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了POI setCellStyle 没有效果相关的知识,希望对你有一定的参考价值。

HSSFWorkbook outWB = new HSSFWorkbook();
HSSFSheet outSheet = outWB.createSheet("Sheet1");
HSSFRow outFstRow = outSheet.createRow((short)0);
HSSFRow outRow = outSheet.createRow((short)1);

HSSFCellStyle cellStyle = outWB.createCellStyle();
HSSFCellStyle cellStyleclor = outWB.createCellStyle();

cellStyleclor.setFillForegroundColor(HSSFColor.RED.index);
cellStyleclor.setFillBackgroundColor(HSSFColor.BLUE.index);

for(int m=0;m<columnList.size();m++)
column =columnList.get(m)+"";
HSSFCell outCell = outFstRow.createCell((short)m);
outCell.setCellValue(column);
outCell.setCellStyle(cellStyleclor);



为什么出来的 excel 单元格 颜色没变化? 我哪写错了?

参考技术A 好像都对着呢。我也这么写的
----------------------------------------------------------------
setFillBackgroundColor(HSSFColor.GREEN.index);
//设定单元个背景颜色

style.setFillForegroundColor(HSSFColor.RED.index);
//设置单元格显示颜色本回答被提问者采纳
参考技术B 你没用实体点填充,所以颜色出不来。
cellStyleclor.setFillPattern(HSSFCellStyle.SOLID_FOREGROUND);<——加上这个

cellStyleclor.setFillForegroundColor(HSSFColor.RED.index);
参考技术C 你好。楼主。我专门来骂你的。
真想用最脏的话来形容你。NM%$#^%#你个大S……%¥&之类的。
我看见你好几处帖子不回。解决了也不说怎么解决了。你这种人,真让人恶心。

poi导入excel

Spring+SpringMVC+Maven+MyBatis+Mysql此环境下的POI导入

此文档讲解Excel导入的功能

 

 

1.1 POI导入excel
