Set datasheet column header text (without using labels in the underlying form)

Question

We have a form in MS-Access which can be viewed either in form or datasheet mode.

The form is arranged in such a way that labels aren't required for some of the textboxes.

In datasheet mode however, some kind of column heading is required and the default behaviour which takes the control name (as in txtRetailPrice) is really ugly.

Is there a way to set the datasheet column header text without putting labels on the underlying form. As I've said, the form is nicely laid out and adding labels in there would actually be confusing.

I'm hoping there is a solution preferably which doesn't involve adding redundant labels to the form.
