This template is designed to be used on Youth Olympic-related tables. It creates the table header where the competing years of specific sport at the Summer or Winter Youth Olympics took part. Recommended to proceed with {{YouthOlympicNationRow}}.
The template code is developed so that:
Cells corresponding to a sport's Olympic non-competing years appear shaded in gray;
{{YouthOlympicYearHeader|season=|sport=|header=}}
season

sport
