The INTERNET Database of Periodic Tables
There are hundreds of periodic tables in web space, but there is only one comprehensive database of periodic tables & periodic system formulations. If you know of an interesting periodic table that is missing, please contact the database curator: Dr Mark R Leach.
The 8 Periodic Tables most recently added to the database:
van Spronsen Periodic Table
From the van Spronsen book, The Periodic System of Chemical Elements: A History of the First Hundred Years:
Mazurs Periodic System of Chemical Elements
A foldout from the Mazurs book, Graphical Representations of The Periodic System During 100 Years.
Mazurs said he drew it in 1967 and published it in 1969: ref. E Mazurs, A new numeration of periods in the periodic system and the Kessler Principle for the construction of the periodic table, Canad. Chem. Edu. 4(3), 21-23, 1969.
It is a Janet's modified system to show the irregularities – Lu, Cr, Pd etc. Click here for a larger version:

Muradjan's Mathematical Structure of The Periodic Table
From the website periodictablemathstructure:
The Periodic Table with a new double numerical structure, presented here is attempt to find table form which will in some new way represent the periodicity and symmetry of the Elements, with the Periodic System as base. Also this tetrahedral laminar table structure maybe will became a base for developing a new shell structure of atomic nucleus. This new rearrangement of the chemical element is based on mathematical formula which result is simple, length of the periods:

Averaged Ionisation Potential Periodic Table
By Leland Allen, a representation of the periodic table with the third dimension of energy derived from the averaged ionisation potentials of the s and p electrons. (Allen suggested that this was a direct measure of electronegativity). From J. Am. Chem. Soc. 1989, 111, 9004:
Electronic Configuration Periodic Table
From the Encyclopedia of Metalloproteins, page 1407 published by Springer, 2013 (ISBN: 978-1-4614-1532-9) a periodic table of electronic configurations:
