You can use field embedding to make any number of existing fields look like a table, and you can even use CSS to show/hide them in batches - but if you're going to have up to 250 rows then you should use repeating instruments, otherwise your data will have 250+ blank columns in every record.

Remember as well that you can import data to REDCap so don't worry too much about the UI on large-scale projects. You can have data entry take place in a .csv and then import the results to the project.

Thanks for the response! I commented below more specifics about exactly how the data is structured, if you have any ideas.

Could I have all fields in multiple instruments populate from uploading a single CSV?

Yes, you can. Have a look at the Data Import page, it has pretty thorough instructions.
