Every enrichment ships off on this page. Tick boxes in
the panel on the right to enable them one at a time, then click the
GS toggle on a table to inject the lozenges. Your
selections persist in #gs.e=... and localStorage
— clear them with the panel's reset action or open the page in a private
window for a fresh start.
The Quarterly sales table below has five numeric columns and a
proper header row, so it qualifies for the virtual-column enrichments: tick
cumulative, diff-compare, or sparkline,
click its GS toggle, then use the Σ /
Δ / ⌇ lozenges. The two smaller tables don't
have enough numeric columns for sparkline or compare.
