Periodic table is just a table which includes all the elements which exist on Earth and in space. I mean, those elements which we know at this moment. We can predict elements by observing and studying more about chemistry properties and knowledge.
Periodic table is NOT 孫子兵法, it has no 最深境界. Just like you memorize the math multiply table, 1x1 =1 1x2=2 1x3=3............
In a periodic table, the elements are well put in descending order from proton number 1 to (for now only to 114). which means, the highest protons of element only has 114 ( as scientists discovered ).
I hope the above information will help. Email me if u had any questions,
