Newlands and Dobereiner.
Newlands did the Law of Octaves.
Dobereiner did the Triads.
Meyer developed a table that was similar to modern periodic table. But his work was published later after Mendeleev.
Meyer developed a table of elements which closely resembles modern periodic table. However his work was published after Mendeleev.
Unknown to Mendeleev, Lothar Meyer was also working on a periodic table. Although his work was published in 1864, and was done independently of Mendeleev, few historians regard him as an equal co-creator of the periodic table.
Mendeleev's published the periodic table in 1869.
Because noble gases were not discovered when Mendeleev formulated his periodic table

He helped create the periodic table but Mendeleev beat him to it.

Dmitri Mendeleev is credited with designing the original periodic table in 1869. He organized the elements based on their atomic mass and chemical properties, which laid the foundation for the modern periodic table.

Dmitri Mendeleev and Julius Lothar Meyer independently published there versions of the Periodic Table between 1869 and 1870. Mendeleev's version would become the foundation of the table used today.
The periodic table was independently proposed by Dmitri Mendeleev and Lothar Meyer in the 1860s. Mendeleev is often credited as the primary architect due to his comprehensive organization and predictions of undiscovered elements.
