您好，猜测有可能是FilePreviewer等插件版本的问题导致出现这个问题的，您可以先升级一下工程文件中使用的插件，检测一下是否是最新版的插件，您可以在这个链接中下载新版本的官方插件商品详情 (grapecity.com.cn)，也可以在这个链接中下载新版本的个人插件商品详情 (grapecity.com.cn)。这个问题是偶尔出现的，还是可以稳定复现的呢？如果可以稳定复现的话，麻烦您提供一下出现这个问题的工程文件，便于我们分析和排查问题，希望可以更好地帮助到您！

另外，您也可以尝试使用7.0.103版本的设计器看看有无此问题，因为新版本会修复一些旧版本出现的问题。

大佬分析的很准确，确实是FilePreviewer造成的问题。附件是工程文件，点击“提取文件”就会报错。删除FilePreviewer控件后，导出表格功能恢复正常。目前我用的插件就是最新的7.0.102.0

您好，经过测试在7.0.103版本的设计器中没有出现异常呢，建议您参考1L回复中多个版本的设计器共存里面的内容，安装一下7.0.103版本的设计器看看是否还存在此问题，因为新版本会修复一些旧版本出现的问题。

公司服务器无法连接外网，每次升级设计器和服务器都要做离线激活，比较麻烦。
先用普通的附件模块代替FilePreviewer吧，等升级到活字格8再解决这个问题。
