You'll have to find where your studs are located and put your mounting screws in them. I wouldn't mount anything that heavy on just the sheetrock, it will fall off.

Mike C thank you so much for the comment. so you wont advise to mount entertainment table on dry wall

No, there are 2X4s located behind the sheetrock, typically 16 inches on center. The mounting screws for the entertainment table need to be into those 2X4s. The screws also have to be of sufficient length to go through the table and the sheetrock. A stud finder will help to locate the studs.

Thank you so much for the explanation.

The description for the center mentions "Recommended for Brick and Concrete Walls.", specifically says not for dry (sheetrock) walls. Looking at the instructions, and seeing how it is attached I might personally try it, but you need the skills necessary to do this.
