It looks the same as it did when Mendeleev created it. There are no changes made to the table throughout the years because Mendeleev had predicted the correct placement for all of our current known elements.
Dmitri Mendeleev was a Russian chemist who proposed the Periodic Law. He published the first periodic table of the chemical elements in 1869, based on the increasing atomic masses of the different elements.
By grouping the elements on the Periodic Table.
He left gaps for the new elements. The properties could be estimated from the space left by him.
See the link below fot the IUPAC model of the periodic table of elements.
it has elements
In Mendeleev's periodic table, the elements were arranged in the increasing order of their atomic masses and repeating periodic properties.

Dmitri Mendeleev was a Russian chemist; he proposed the modern Periodic Table of elements in 1869.
Mendeleev predicted that properties of elements are periodic function of atomic mass. He demonstrated it by creating a table.

To understand the concept of Periodic Table
Because the properties of the elements change in a periodic fashion. In the early versions, when fewer elements were known, the chemically similar elements were thought to occur every eight positions.
