HTML: fixed table header with scrollable data (Angular?)

Having fixed / floating header in a table is not easy even in Excel.
It should be, that is an obvious use-case.

After 20+ years, HTML still does not have an universal, easy, declarative or plug-in solution either, to preserve semantics of a data table.
Most "solutions" fix width of columns, reducing flexibility of HTML tables, and require investigations, plugins, testing...
Time to add this to HTML6 or as Angular "directives"?
