Columns
Beyond the funnel bars, the visual can draw up to 8 extra data columns to the right of the funnel, one cell per step — for metrics that don't belong on the bar itself (NPS, satisfaction, repeat-purchase rate, a second product line…).
Columns are configured through the Additional Table card, edited via a ⚙ gear-icon dialog on the visual rather than typed into the Format pane directly — see Additional Table for the editor itself and the full field list. This page covers the concepts shared by every column, regardless of its settings.
Turning columns on
Global Settings → Options → Show extra columns must be on for any configured column to render.
Continuous vs. Discrete columns
Score type controls what kind of value the column holds:
- Continuous (default) — a numeric measure. Base, Comparison, Comparison base, Precision, Display and the above/below colors are all active, and the column participates in significance testing exactly like the main funnel.
- Discrete — an arbitrary text or ordinal value (e.g.
1st,2nd, a free-text label). The Score measure's raw value is shown as-is, with no rounding, no comparison and no significance coloring — only the column's plain Font color applies. Switching to Discrete hides Base / Comparison / Comparison base / Precision / Display / Color above/below in the Additional Table gear-icon dialog, since they have no meaning for a discrete value.
Display modes
(Continuous columns only — Discrete columns always just show the raw Score value.)
| Mode | What's shown |
|---|---|
| Value | The column's own Score, rounded to Precision decimals |
| Gap | The difference between the column's Score and the main funnel's Score at the same step (+/−, rounded to Precision) |
| Value & Gap | Both — the Score on top, the gap just below, in a slightly smaller font |
| Comparison value | The column's own Comparison measure, rounded to Precision |
| Comparison Gap | The difference between the column's Comparison and its own Score (comparison − score, +/−, rounded to Precision) |
| Comparison Value & Gap | Both — the Comparison value on top, the Comparison Gap just below |
Plain Gap is always computed against the Main Partition's Score at the same step for the same group. Comparison Gap is computed against the column's own Comparison measure instead (comparison − score) — useful when the column's benchmark isn't the main funnel at all (a different category, year, product…).
Column-level significance
Independently from the funnel's leakage significance, each continuous column runs its own two-proportion z-test: the column's Score vs. its own Comparison, using that column's own Significance level and Independence — set per column in the Additional Table dialog's Significance section, not shared with the Leakage card. This matters because a column's Score/Comparison roles don't have to mirror the main funnel's: e.g. a column can use a market-wide average as "Score" and a single brand as "Comparison" — the reverse of how Main Partition is normally wired — and its own Independence setting can be set accordingly (see Leakage → Independence for what the three options mean). The cell text is colored with Color above/below comparison accordingly, or the column's plain font color when the test is inconclusive or the Base/Comparison/Comparison base aren't all set. This coloring applies to whichever display mode is active, including the Comparison-based ones.
Column typography, width and separators
Font, column width, header visibility and separator lines are configured per column in the Additional Table gear-icon dialog, alongside the measures and display mode.
Every column but the last one has a neighbour to its right, so a value slightly too wide for its cell simply encroaches on that neighbour's padding. The last column has nothing to its right except the edge of the visual, so the layout automatically widens it — never below your configured Column width (px) — to fit its own widest rendered value or gap, plus room for the conversion picto when that option is on. A figure crossing into an extra digit therefore stays inside the visual instead of being clipped.
