Hello, Are you referring to the table functionality, which works great in notebook and maybe also now in the cloud? This sounds like what you're saying, which is an often-requested thing that finally is top level (previously was html.table, which also still works). I did not know about this

I did not know about this function (thanks!) though I had something different in mind, i.e.:emphasize *some* elements of a list. What Volker would define as: table(range(100), highlight=is_prime) Right, I see what you mean now. In principle the LaTeX and other outputs of table
