My question is how did it regroup?

Surface tension tries to minimize the surface area by pulling the puddle into the smallest volume.

Your table may not be perfectly flat, and water would tend to gather in the low location.
But also, water has surface tension, that is that the surface of the medium wants to contain the fluid inside, as if there was a membrane. This means that two water droplets will gladly merge wen coming into contact. And slowly, drops of water will get larger as they gather smaller ones, until there is one large puddle.

surface tension. For small quantities of water, this is the force that cause it to "stick together," for example, to form a drop when it is falling through the air. When there is more water, then it will not come back together, rather it will spread.

your desk may not be perfectly level (not in all spots, at least). if they have any mobility from gravity from being on a slope, surface tension will do the rest.
take a look at these vids on surface tension of water in space. its really fascinating and the astronaut giving the demonstration is pretty knowledgeable, youll probably learn something

Your question is not clear, but if two drops of water touch each other, they merge to form a bigger drop, but which is smaller than the two drops.
