Not if this is the heading for Table View. This is one of the reasons that I prefer List View--which can be used to produce a similar table format view of data, over Table View for presenting info to the general user. In List view, the field labels/column headers are layout text and you can edit them on that layout to be whatever you need them to be. You aren't locked into the field name assigned to it in the table definition.
Done that now, so much appreciated.
