Hi @alasaadstat,
This is a bug in @ptconf. The macro is being expanded to:
julia> @macroexpand @ptconf tf = tf_compact2
:(PrettyTables.set_pt_conf!(PrettyTables._pt_conf, tf = PrettyTables.tf_compact2))
That’s why you can’t use custom formats. In fact, even custom highlighters will not work. I will try to fix it.
