Jak zaimplementować numerację wierszy w h: dataTable
Mam tę tabelę JSF z podziałem na strony.

</code>Stworzyłem prosty przykład liczby wierszy, aby przedstawić liczbę wierszy z bardzo prostą tabelą html. Do drugiej tabeli działa paginacja, ale nie wiem, jak ją wdrożyćui:repeat wh:dataTable w celu wdrożenia liczby wierszy. Jak mogę to wdrożyć?
