Booking grid table GUI

Question

Hello

I'm working on a booking site, and I have problems with the GUI.
How can I/should I build a grid/table displaying the information.

The columns are: Monday - Sunday
The Rows are: First available time - Last available time

The times available are set by admin and do not have start/end at the same time every day.

Each cell in the grid should contain a button or a link so the user can book/select available times.
On the admin pages each cell should contain a control for creating a bookable time (if the time is unavailable) or an control for removing a available time.

Im working in C#/ASP.NET.

Any suggestions?
