异常代码

           EasyExcel.read(is, clazz, listener).extraRead(CellExtraTypeEnum.MERGE).sheet().doRead();

问题描述

代码没变的情况下，文件一个是自己手动创建的模版，一个是代码导出的。读取合并单元格，手动创建的读取出来第二列及后面的列，对象中是不会有合并单元格的值的。代码导出的文件则读取出来对象中每一列都包含合并单元格的信息，我不知道是什么原因导致了这样，是否有方法可以控制这个。 image image image

Research direction
Investigate EasyExcel's merge cell reading logic by examining the CellExtraTypeEnum.MERGE handler. Compare the Excel files manually created vs code generated using a binary diff tool to identify formatting differences. Check the library's test cases for merge cell scenarios, particularly in the read package. Look for any assumptions about cell values in merged regions that might differ between file generation methods.
