+# Decision: Status Table Columns Use Icon-Only Presentation
+
+**Date:** 2026-04-22
+**Status:** active
+
+## Context
+
+Dense hardware tables frequently repeat the same `status` values.
+
+Showing a textual `status` header and textual badges in every row wastes horizontal space and reduces scan speed, especially in sensor subtables.
+
+The viewer still needs to keep status meaning explicit and avoid relying on color alone.
+
+## Decision
+
+Table columns named `status` render as compact icon-only columns.
+
+This includes:
+
+- an empty visible header cell for the `status` column
+- a minimal-width table column sized for the pictogram
+- a glyph plus color to distinguish state
+- accessible labeling that preserves the raw status value without showing repeated text in the cell
+
+Object sections may continue to show status as a regular field value.
+
+## Consequences
+
+- Table layouts gain more room for source fields such as `name`, `model`, and `location`.
+- Status meaning remains available to assistive technologies even when the visible cell is icon-only.
+- Future table UI work should keep `status` compact instead of reintroducing wide text badges by default.
