Mendeleev's table was arranged by Atomic Mass and the periodic table is arranged by protons (atomic number).
Mendeleev predicted that properties of elements are periodic function of atomic mass. He demonstrated it by creating a table.

There is no difference between "period table" and "periodic table" - they refer to the same thing. The periodic table is a tabular display of the chemical elements organized by atomic number, electron configuration, and recurring chemical properties.
He left too many spaces between the elements......
Mendeleev's periodic table was particularly special because it organized elements based on atomic mass and their chemical properties, revealing a periodicity that highlighted the relationships between them. He left gaps for undiscovered elements, predicting their properties, which demonstrated the table's utility and foresight. His work laid the foundation for the modern periodic table, emphasizing the importance of atomic structure and periodic trends in chemistry.
To understand the concept of Periodic Table
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's periodic table arranged elements by increasing atomic mass and grouped elements with similar properties together. Today's periodic table is similar, but it is arranged by increasing atomic number, which reflects the number of protons in an atom's nucleus. Both tables also show periodic trends in properties as you move across and down the table.
The difference between a period and a group is that:A periodic is a horizontal row of elements in the periodic table, which simply means the column of the periodic table.A group is a vertical row of elements in the periodic table, which simply means the row of the periodic table.
Actually, Dmitri Mendeleev formulated the periodic law and published his periodic table of elements in 1869. This table arranged elements by increasing atomic mass and grouped them based on similar properties, predicting the properties of missing elements. It was a significant contribution to the field of chemistry.
