【问题描述】：
使用 XSLT 将 XML 转换为 Excel 并在尝试在 Excel 中打开生成的 XML 时收到以下错误。根据研究和相关帖子Error : Exporting excel through XSLT，错误似乎是由于使用 MergeDown() 后行/单元格索引不正确。出于某种原因，在未指定任何索引的情况下使用 MergeAcross() 就可以正常工作。
我还没有找到一种方法来索引行，因为特定的单元格被合并到一个不同的数字上，这取决于每个单元格可能不同的变量值，所以在我的 xslt 中没有简单的方法定义我找到的每一行的索引应该是什么。请在下面找到 xslt、源 xml 和所需的 xml。提前感谢您的帮助。
