I figured it out.
You need to use "Resultsets" as input to the "Create CSV Table".
Then go into code view and find:
"from": "@Tomas Podoba ('Execute_stored_procedure_(V2)')['resultsets']"
change it to this:
"from": "@Tomas Podoba ('Execute_stored_procedure_(V2)')['resultsets']['Table1']"
I had mistakenly assumed that SQL Server and stored procs would work out-of-the-box with Logic Apps.
