According to both an on-line taxi fare calculator (http:/www.worldtaximeter.com/london), and a on-line journey planner (http:/maps.google.co.uk), London City Airport (only 12 miles away) would be the closest airport to St Pancras. The only potential problem is that London City is a relatively small airport, only servicing a limited number of locations, so may not be of any use to you, depending on where you're coming from.
