Reading and combining multiple CSV files with varying number of columns and rows

Hi All,

I am trying to import multiple CSV files and try to combine them into one table. I was trying to use loop nodes to perform this task but got an error. I think it is probably something simple but I do not know how to solve it. Does anyone have a clue and point me in the right direction? I also created and uploaded some dummy files and workflow to represent the files I am dealing with. Thank you for your support.
