Please add support for escaping html characters when copied to other sheet softwares

[Nvocmoc]

Hi Developers, thanks for the wonderful work!

I'm heavily using this plugin to preview the results, then usually I need to copy the sheet into other sheet softwares such as Google Sheets/Microsoft Excel. The issue is that, even though some special characters such as "<", ">" are displayed correctly in the VSCode, after pasting the whole sheet into the aforementioned softwares, these characters are un-escaped, becoming "& lt;" and "& gt;".

Can you please check the issue and provide a fix? Would really appreciate it. Thanks!
