what is the position of isotopes in the modern periodic table

Periodic table is based on atomic number. Since, all thtopes of an element have same atomic number, they have not given any specific position.
Isotopes are atoms of the same element having different atomic mass but same atomic number. For e.g., there are three isotopes of hydrogen with atomic mass 1, 2, and 3. According to Mendeleev's periodic table these should be placed at three separate places. However isotopes have not been given separate places in the periodic table.
