This lgtm—but it looks like we need to update the build matrix for Ubuntu since lipgloss is on 1.18 now.

Looks like this doesn't compile anymore (I think because the table API has since changed). @maaslalani do you mind updating accordingly so we can get this in?

Fixed the example to compile, Headers API was changed to accept string.
