Answer 1

The shared data provided is pretty vague, so I will show my own (with field names on the first line)

"EmployeeName", "WeekNumber", "DayOfWeek", "HoursWorked"
"John Doe", 20, "Monday", 8
"John Doe", 20, "Tuesday", 8
"John Doe", 20, "Wednesday", 8
"John Doe", 21, "Thursday", 8
"John Doe", 21, "Friday", 8
"Jane Doe", 20, "Monday", 8
"Jane Doe", 20, "Tuesday", 8
"Jane Doe",21,"Wednesday",8
"Jane Doe",21,"Thursday",8
"Jane Doe",21,"Friday",8

      Monday       8 hours
      Tuesday      8 hours
      Wednesday    8 hours
   Week: 21
      Thursday     8 hours
      Friday       8 hours
