any thoughts on this @khalidabuhakmeh ?
if you're not able to add this maybe i can collaborate and add it myself if that's ok for you?

I would also be interested in something like this. It would also be good to have foreground colour support.

Unfortunately, people are happy to use code other people wrote, but contributing to it is asking far too much. 😁

It's cool, I know folks are busy.

I recommend folks check out https://github.com/spectresystems/spectre.console.

ConsoleTables was a hobby project. Patrik has definitely done a great job and I've contributed a few ideas there. .NET OSS for the win. :)
