Moving table view cells down without moving tableview's origin

I want to be able to move/shift the group of UITableViewCells in the UITableView downward, without scrolling the tableView, and without moving the entire tableview downward. The desired effect is that there is an amount of whitespace above the table view cells after they're placed in the table view, and when the user scrolls down through the table view, the white space is covered by the cells.

You could use a tableView header and adjust its size. After changing its size, call:

[tableView reloadData];

If you want to animate the size change, try calling:

[tableView beginUpdates];
[tableView endUpdates];

After changing the header's size.

EDIT 1:

As opposed to a table view header, you could use a static cell as mentioned in the other answer. To animate the size change, use the steps above. Change the size in:

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath

Don't forget that a UITableView is a subclass of UIScrollView.

And that UIScrollView have this property.

contentInset
The distance that the content view is inset from the enclosing scroll view.
@property(nonatomic) UIEdgeInsets contentInset
Discussion
Use this property to add to the scrolling area around the content. The unit of size is points. The default value is UIEdgeInsetsZero.

I don't fully understand what you are trying to do, so I just hope that this is what you are looking for.

After Question was Edited

Add an empty cell where you want it to be and adjust it's size when needed.
You will need to make some try about doing it animated (using insert and reloadCell) or using the reloadData option of the tableView to get the visual you want.
