Is there a way to erase contents in cells more than one, without deleting the formatted background?

When using Numbers on iPad (Numbers '09, v2.3 on iPad, iOS v6.1.3), I want to erase contents in an area with more than 1 cell, e.g. 10 cells, without erasing/deleting the formatted background colour.

Using a right click on cells using Numbers on a Mac (Mac, OS X v10.8.4) you can differentiate between "delete content of cell" (where the background is maintained) and "delete all" (where both the content AND the background is deleted).

Please, I need help.

Kindly,
