我已经开始使用Open XML创建Excel文件,以便向其中添加一些数据。我所包含的示例文件是我在网上找到的示例的修改版本。它创建了excel文件,但是当我尝试打开它时,它给了我三个错误。我怀疑最后两个错误是由于为标题单元添加StyleIndex,但是当我打开任何Excel文件时,最近出现第一个错误。打开由XML创建的Excel文件时出错
1-无法使用对象链接和嵌入。
2- Excel在'SheetPInfo.xlsx'中发现不可读的内容。是否要恢复此工作簿的内容?如果您信任此工作簿的来源,请单击是。
3-Excel能够通过修复或删除不可读的内容来打开文件。 修复记录:/xl/worksheets/sheet.xml中的单元信息部分
在关闭最后一条错误消息后,我还获取了文件中的数据/数组,但StyleIndex(大字体)未出现在标题单元格中'姓'。
什么可能是错的?当我在线搜索时,行的顺序对于Excel非常重要,所以我想也许我的StyleIndex相关行出错了。
任何帮助将不胜感激。
