My graduation project is to build an educational management system website, but it is stuck in the timetable display.

This is my database field design. I mainly don’t know how to display it on the front end.
For example, the compilation technology course is taught in periods 3 to 5 on Tuesday, and then the compilation technology course will be displayed in periods 3 to 5 in this table, but the general table shows one row of tr, so I don’t know. How can I display this to three vertical lines (sections 3 to 5). .
