I've tried generalizing a few examples I've found online with my own code, but I can't seem to get any data to add to the table. The columns add just fine. Some insight on how this works would be helpful. I've already picked my may through the API that relates to tables and I still can't seem to get it to work.
What I want to happen is for the user to click the add button, to select the file(s) and for the data to be added to the table. The only things that get added are the column names.
