Complex Table Toolbar
Complex Table Toolbar is a free Chrome browser extension built for accessibility professionals, developers, and QA teams. It provides a powerful side panel that lets you inspect any HTML data table on any webpage — revealing header mappings, scope attributes, ARIA roles, cell associations, and WCAG 2.2 compliance issues in real time.
What It Does
Features
Table Header Analysis
Instantly visualize all <th> elements, their scope attributes, and how they map to data cells across complex multi-level tables.
Scope Inspection
Detect missing, incorrect, or ambiguous scope attributes (col, row, colgroup, rowgroup) that break screen reader navigation.
Association Visualization
See exactly which headers are associated with each data cell via headers/id relationships, with color-coded overlays.
WCAG Table Audit
Automated checks against WCAG 2.2 success criteria 1.3.1 (Info and Relationships) and 4.1.2 (Name, Role, Value) for tables.
Screen Reader Simulation
Preview how a screen reader would announce each cell, including the full header chain, to catch issues before users do.
ARIA Grid Support
Inspect role="grid", role="treegrid", and role="table" ARIA patterns alongside native HTML tables.
