As the name indicates it is "periodic" meaning it repeats.
Russian guy called Mendeleev noticed that certain elements have similar properties. We now know this has to do with valance electrons - can't remember if he knew this.
So he set up this grid of elements with similar properties in columns and in increasing order of atomic weight left to right. This gives the table we know and love.
He was actually able to leave blanks for things that we hadn't discovered becasue he was so sure of the pattern he saw emerging.
Other tables exist.
