此表在表中变形，实际上Outlook客户端软件中没有右端td边框，我正在使用Windows 10，Outlook 2016，使用UiPath对其进行测试。我使用了putsmail.com，但效果很好
请帮助专家。

Desktop Outlook 2007、2010、2013、2016和2019使用Word的HTML呈现代码，而在Web上由用户的浏览器就地呈现。
Outlook 97-2003使用mshtml.dll（又名Trident，Internet Explorer的引擎）来呈现HTML电子邮件。由于Outlook使用Word编写HTML电子邮件，但使用Internet Explorer查看它们，因此这使Outlook用户的电子邮件外观不一致-微软的决定是使用Word进行撰写和查看-我认为这是阻止HTML的巨大错误电子邮件已经发展了数十年，并一直受到阻碍，因为它现在是最低的公分母（这是因为Word对HTML和CSS功能的支持几乎超出了Internet Explorer 5.x所支持的范围，因此请不要使用Flexbox和CSS Grids之类的东西）。
