# Tabular intent requires data-table conditions
|
|
|
|
## Description
|
|
|
|
The most common accessibility bug in grid layouts is partially following the data-table conventions. A developer arranges fields with **tabular intent** — one field acts as a label or row header for another — but the grid does not satisfy all the data-table heuristic conditions. The client falls back to layout-table rendering, and the tabular relationships between fields are lost: a screen reader announces each field independently with no programmatic association.
|
|
|
|
Flag a grid as an accessibility issue when any of these are true:
|
|
|
|
- An editable field has `ShowCaption = false` and the grid does not meet all data-table conditions.
|
|
- Fields are arranged so that one field is clearly intended to label or describe another field (tabular data intent), but the grid does not meet all data-table conditions.
|
|
|
|
Both manifestations have the same root cause: tabular semantics were intended but the heuristic ultimately rendered the grid as a layout table.
|
|
|
|
## Anti Pattern
|
|
|
|
A single field that keeps its visible caption is enough to demote an entire would-be data-table grid into a layout table — and silently strip the labels off its sibling captionless fields. Either restructure to meet all three conditions, or restore captions on every editable field.
