Acceptance Criteria

GIVEN stratified user csv data has been fetched and at least 1 upload exists in db
THEN a table should display csv file according to prototype
AND each row should have the following design:

Headers: Stratification factor | Summary  | Action buttons (download / delete )

Rows: “Stratification on FRL (437=“Yes”; 563=“No”)" [for each strata represented, so this could be unknown number of lines long]

Notes
Action button functionality in separate story, for this task the buttons should be positioned w/o doing functionality

[ 🟠 verify that this idea is no longer the desired design] Also note design below, @amurphy-cl mentioned this as the original concept as she imagined it. This is similar but conceptually it may mean storing data in a different way, with a tag to indicate a grouping of UUIDs that were uploaded together. In this design, each row would represent that tagged group, with a summary of the strata breakdown in that group instead of each row = 1 unique strata and a summary of all strata values from all groups.
