十万火急!POI不能准确读取excel批注 求高人帮助!

10-01-05 tanyongji

试了很久都没法实现这个555 一开始还以为很简单的~ 详情如下

我用了POI读取excel单元格值和相应的批注。我是在工作表逐行循环,每一行再循环每个cell,

如果当前cell的批注不为空,就显示当前cell的内容和相应的批注,cell的内容的确是按每行搜索,

但是如果cell的单元格是公式,当读取当前cell的批注cell.getCellComment().getString().toString()并不是按每行搜索,而是按列搜索出来。我看过很多次代码都不清楚是哪里的问题, 请高手们帮忙下 先谢谢了!
