I personally use Bootstrap Table because it allows me to sort and paginate when I have a large set of data. It also allows users to scroll left and right as @scoobie has mentioned.
I usually convert my CSV file into a HTML table with Bootstrap configurations with a click of a button using my pre-written python code (http://blog.victoriaxie.com/eng/2015/9/10/a-simple-way-to-convert-csv-data-into-a-sortable-bootstraphtml-table-using-python). For Squarespace user, there is a caveat-- because the Bootstrap CSS may conflict with Squarespace's font, depending on your template, you may need to manually configure the font in the custom CSS window. I took the effort to readjust the font with custom CSS because it is worth the time in the long run as I will have quite a few of large tables, but I understand it is not worth everybody's time.
