table

Q: I’ve been told eating on a dining table is ‘haram’. However both me and my wife suffer from lumbar disk spondylosis and are under medical advisement to not exert ourselves too much. She can’t sit, stand or squat for a prolonged period of time. So for convenience and health’s sake my family dines on a table. Please clarify if it is indeed haram to eat in this manner and if permissible what are the conditions for it?
