Teams ont included in header column on grading page

[madclam]

In the new version for large table, the student name column is static, but not the teams.
The teams should also be static.

On that same page, the CSV file

• does not include the teams
• has grades noted as 5/20, which is inconvenient. Better add a row indicating "graded over" and indicate "20" then show in each row the actual grade
• does not show the details of the grade break-up
