The periodic table consists of various bits of information for the elements. Most notably, and simply put, is the Atomic Number. The word in itself bares no striking resemblance to what it means--besides that its an atomic property.
Henry proposed that each natural number is a real element (at least within a realistic range, obviously he did not mean 4e10 could be a real atomic number). This factual bit led to contribute to the periodic table majorly.
Periodic Law states that going by atomic number would allow logical groupings based on properties to recur regularly.
