INTERNET Database of Periodic Tables
There are hundreds of periodic tables in web space.... but only one comprehensive database of periodic tables & periodic table formulations. If you know of an interesting periodic table that you think should be added to the database, please contact Mark Leach.
Periodic Table formulations from the years before 1900, by date: 1000BC Elements Known To The Ancients Ten elements were known to the ancients: carbon, sulfur, iron, copper, silver, tin, platinum, gold, mercury and lead. Carbon and iron were known in the iron age, copper and tin in the bronze age and platinum was known in Aztec culture:
450BC Classical Elements The Greek Classical Elements — Earth, Water, Air, Fire and Aether — date from 450 BC or so, and persisted throughout the Middle Ages and into the Renaissance, deeply influencing European thought and culture. Plato characterizes the elements from a list created by the Sicilian philosopher Empedocles called these the four "roots." Plato seems to have been the first to use the term element:
1682 Kenelm Digby's A Choice Collection of Rare Secrets 1718 von Francois Etienne Geoffroy's Tabelle relativer Affinitätsstärken
1778 Diderot's Alchemical Chart of Affinities 1789 Antoine Lavoisier Antoine Lavoisier's produced the first modern list of chemical elements, containing among others, the 23 elements of those known then. He also redefined the term "element". Previously the metals, except mercury, were not considered elements. Wikipedia A list of 33 simple substances compiled by Lavoisier, from Traite? Ele?mentaire de Chimie, Cuchet, Paris, 1789, p. 192:
From Peter van der Krogt's Elementymology & Elements Multidict web site:
1800 Elements Known in The Year 1800 Some 27 elements were known by 1800. This was enough to understand that an element was in some way special and that compounds were made from elements, but not enough to construct a comprehensive periodic table:

1843 Gmelin's System L. Gmelin, Handbuch der anorganischen chemie 4th ed., Heidelberg, 1843, vol. 1, p. 52:
1850 Johann Dobereiner's Triads (1780 - 1849) Triads are found with sequence of three similar elements, where the middle element has a mass equal to the average of the least and most massive. The diagram below, updated from here, uses mid-nineteenth century atomic mass information rather than modern data. If atomic numbers (Z) are used (a property unknown in 1850), the triads are exact: 1862 The French geologist , Alexandre-Émile Béguyer de Chancourtois was the first person to make use of atomic weights to produce a classification of periodicity. He drew the elements as a continuous spiral around a metal cylinder divided into 16 parts. The atomic weight of oxygen was taken as 16 and was used as the standard against which all the other elements were compared. Tellurium was situated at the centre, prompting vis tellurique, or telluric screw. Chancourtois' original formulation includes elements in their correct places, selected compounds and some elements in more than one place. The helix was an important advance in that it introduced the concept of periodicity, but it was flawed. The formulation was rediscovered in the 1889 (P. J. Hartog, "A First Foreshadowing of the Periodic Law" Nature 46, 186-8 (1889)), and since then it has appeared most often in a simplified form that emphasizes the virtues and eliminates its flaws.

Newland noticed that if he broke up his list of elements into groups of seven starting a new row with the eighth element the first element in each of those groups had similar chemistry. More here.

1870 Meyer's Periodic Table. This is rather similar to the Mendeleev attempt at the same time. 1870 Baumhauer's Spiral
1871 Mendeleev's Tablelle II Mendeleev's Tabelle II in semi-modern Form: To the modern eye, the 1869/71 formulations lacks any Group 18 rare gases and there are few f-block elements: The success of the Mendeleev periodic table can be attributed to the gaps which Mendeleev predicted would contain undiscovered elements with predictable properties. Mendeleev named these unknown elements using the terms eka, dvi and tri, from the ancient Indian language of Sanskrit:
