Here is a workflow for this step of my process. http://www.editorial-workflows.com/workflow/5771846762889216/xI4LXsctvGg
The csv is exported from iOS Numbers into editorial. This workflow takes the file contents of that csv (which is default named Blank.csv) and converts it to a mmd table, adds borders in the HTML step. Replaces the csv text with the mmd table... and in the shared workflow outputs to a PDF file. I'll save that step until I'm done with the whole report.
All python thanks to @ccc , who is effing fantastic.
