Please help me with a table

The table compares people in various jobs in terms of their sleeping habits, which are observed in a Canadian survey.

Overall, what stands out from the table is that students and business executives have long, undisturbed sleeps, while truck drivers have the most discontinued sleeping hours.

Looking at the details, as regards students, full-time mothers, they sleep for 8 hours. Whereas students sleep from 11 pm to 7 am, mothers are awake between 1 am and 3 am. Instead, they will have a two-hour nap starting at 1 pm.

By contrast, truck drivers, business executives and doctors sleep under 6 hours a day. People who drive trucks have two separate sleeps lasting for 3 hours, with the figure being the same for the second sleep of doctors. Doctors also have another previous sleep from 1 pm to 3 pm. In total, they sleep for 5 hours, the length of which is equivalent to business administrators. Nevertheless, they just sleep once per day.
