Not sure where to start?

Then once the whole list has the same as what is in the output section above I can just split that into 1 string for each table?

Probably just make a list of lists. Create a main list before you start iterating through files. Then create a list inside for each file and append the lines to it. Then finally append that list onto the main list.

Try to write it and then we can work out the details.
