I'm less interested about web, but I think tables would work well for shell/terminal. If you squint, stream-of-objects and tables are sort of similar, so with some sort of PS/nushell style environment having a terminal with native table rendering ability could be great. I think lot of stuff we interact with in shell tends to be somewhat tabular in nature, but is now getting muddied by formatting it for dumb text terminals.

Just look at the first example on nushell frontpage: https://www.nushell.sh/ could that not look better with "Great Tables" or something similar?

Ah… the good old spacer.gif days…
