Enhancement Request:Should improve cell border compatibility with external mail

End user copy table from excel and paste in Notes mail, then sent mail from Notes Release 11.0.1FP9. Which show correctly in Notes mail as below attachment TableInNotes.png.

External mail(for example:QQ,Outlook) user received, the table border display ugly, which show as below attachment TableBorderForExternal.png.

Even thought set the ”MIME format“ for ”Format for messages addressed to internet addresses:“ in location document before sent mail, and select Edit->Pasted Special->HTML to paste excel table,but also no help.

So need improve cell border compatibilty between Notes with external mail. Thanks!
