Microsoft Flow, email with table when .csv is saved in Sharepoint

I pasted this question here and the suggestions have gotten me most of the way there, but I'm having trouble finishing it up could use Stack Overflow's help.

I have a flow that looks like this:

The basics are that I have R run a script once a day. Every once and a while, that R script 'finds' something, and saves a .csv with the results into a sharepoint folder.

I'd love to have Flow email me the results of that .csv. I've already previously figured out how to get Flow to email me a simple notification, or attach the file, but now I'd prefer that the table was IN the email. Something like this:

Where I am now:

I've ALMOST got it to work. The flow will trigger, it'll parse the data, it'll send me a table with some of the data in it, but it'll look messed up. Either like this:

Where all of the csv data is crammed into one column. Or more recently with these settings:

It'll put ALL of the csvdata in every column:

To be honest it makes sense its screwing up like that because you can see in the settings that it says csv data in every column, but if I try 'automatic' columns it fails with "the property 'columns' must be specified unless its an array'.

In summary:

How do I specify what goes into what column?

This looks like a third party action: "Parse CSV". From the result of the subsequent steps, it looks like the contents is in JSON. Therefore, you can use the built-in Parse JSON action to read the output of the "parse CSV" action, after which you can access the individual fields to build the HTML table.
