可能的使用场景
当你将 Excel 文件保存为 HTML 时，Aspose.Cells 会显露 Downlevel 条件评论。这些条件评论大多与较旧版本的 IE 相关，与现代浏览器无关。你可以在以下链接详细了解它们。
Aspose.Cells for JavaScript via C++允许通过设置HtmlSaveOptions.disableDownlevelRevealedComments属性为true来消除这些Downlevel Revealed Comments。
在保存为HTML时禁用下级可见的批注
以下示例代码展示了 HtmlSaveOptions.disableDownlevelRevealedComments 属性的用法。截图显示了未将此属性设置为 true 时的效果。请下载此代码用的【示例 Excel 文件】(50528257.xlsx) 和生成的【输出 HTML】(50528258.zip) 以供参考。
