Table column auto-fit measurement: cell icon width · case 02

The table cell icon width result violates the stipulated table column auto-fit measurement contract.

Member previewVariant 2 · 3 implementations · 7 checks per implementation

Case contract

Auto-fit measures only this column’s visible measured cells, includes indentation and cell icons, optionally measures header text plus both controls, takes the widest content, adds two-sided padding and reserved icons, clamps bounds, and reports changes in either direction.

Why this case matters

An offline table UI model isolates table column auto-fit measurement, including adversarial row/column relationships.

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.
