What effect did th discovery of gallium have on the accepteance of mendeleevs table?

Mendeleev had some empty spaces in his table. On being asked why he left spaces, instead of seeing it as a drawback, he confidently said that those were the places for "yet to be discovered elements". He named them by prefixing the Sanskrit numeral "Eka-" to the preceding element.For example, he named Gallium as "Eka-aluminium", Germanium as "Eka-Silicon" and so on. Later, when a new element was found and was named as Gallium, it was observed that it had almost same properties as that of Eka-Aluminium predicted by Mendeleev. As his predictions were almost accurate, other scientists began to accept that his classification was indeed better than any others'. And so, it was accepted.
