Dynamic table incl links

What I am trying to do: Scheduling appointments.
The user creates a schedule, opening and closing time for each day and the number of bookable slots. As an example the user creates a week Mon - Fri from 0800 to 1600 with bookable slots every 30 min. And Sat-Sun 1000-1300. This is added to a database.
The problem: How do I present this in a grid pattern, mon-sun on the horizontal and the time on the vertical (remember that the days can differ). WITH an clickable link/button in each cell that indicates the time that has been clicked on..
Thanks..
