No Enough Cell to Use in UITableview

I have create a UITableview in Storyboard and it is dynamically cell. The problem is that when there is no enough cells to reuse, it randomly empty few of my cells. I think this is logic, but i want to resolve this problem.

I give an example: I have a tableview that is capable to generate 10 cells in a view. But now, i only want to show 8 cells out of 10. It gives no problem when i have only a section. With more than 1 section, it will always empty 2 cells and show 8 cells, but it should show 10 cells.

Can anyone help me with this. Thank you.
