Given that your module is very long, I might suggest dividing the content into two (or more) modules. Also be sure to use text headers to help students find what they need.
Whether or not it's technically possible to build a table with a scroll bar, I see two issues with it:
- students using a mobile device will be frustrated by it (Plus it's easy to scroll through a module on a phone anyways.)
- it won't be accessible to students with visual impairments (It's very cumbersome to read through even simple tables with a screen reader.)
I would suggest putting aside the plan to create a table with a scroll bar and look for other ways to organize your course content so that it's more accessible to your students.
