Why was Mendeleev's decision to leave blank spaces on his table sometime referred to as his most significant contribution to periodic table?

Mendeleev thought about the future and realized that it was entirely unlikely that all earthly elements had been discovered, so he left blank spaces in his table and even predicted some of the elements that would fit in those spaces. Surprisingly enough, as time passed, chemists began discovering many of the elements that he had predicted, which fit perfectly into his Periodic Table.

What was Mendeleevs proposal?

How could you use Mendeleevs periodic table to identitify new elements?
He left gaps for the new elements. The properties could be estimated from the space left by him.
What did Mendeleevs periodic table look like?
It looks the same as it did when Mendeleev created it. There are no changes made to the table throughout the years because Mendeleev had predicted the correct placement for all of our current known elements.
