To detect broken table headers in responsive web grids, inspect the rendered browser DOM using bounding-box comparisons to verify header alignment, catch phantom columns, and identify width mismatches between header and body rows.

Header misalignment in responsive design happens when header and body columns drift out of sync across different viewports, often leaving dead space when the table header renders narrower than its container.

You can find empty action columns and phantom columns in web tables by running column integrity checks on the rendered DOM, which flags empty header cells, width mismatches between rows, and missing table content.

Check if a long data table needs a sticky header or zebra striping by running readability checks on the rendered grid, which flags long tables missing these features to ensure users can browse large datasets easily.

This table layout inspection requires browser DOM inspection to perform bounding-box comparisons and visibility checks. It has no external dependencies and works directly within the rendered interface environment.
