There's going to be the column "retest" in the db, value 0 means first attempt, value 1 means the row is a retest. The task is to visualize it in the UI.
- Display the "➋" emoji in the table header for engines with results marked as "retest=1."
- When the "➋" emoji is clicked, a new column displaying the retest results should appear to the right, and the left-hand column header should shift accordingly (i.e. both columns should have a single common header)
- Clicking the "➋" emoji again will hide the additional column.
