Table header fails in the accessibility check done by the Accessibility Checker tool

Problem: The table header fails the accessibility check in the Accessibility Checker tool after installing Acrobat September 2021 update

What changed

In the earlier versions, Acrobat was unable to detect any missing table headers, and such table headers were shown as passed in the Accessibility Checker tool. With the September 2021 release of Acrobat (version 21.007.20091), PDFs with missing table headers are flagged in the Accessibility Checker and show as failed in the accessibility check result.

Solution: Use proper table header tags in the PDF

Define the table header tags in the PDF so that the Accessibility Checker does not flag it as a fail in the accessibility check result.

Workaround: Create a IgnoreTableHeaderCheck registry key (Windows) or plist file (macOS) where the Accessibility Checker passes the incorrect table header

Atenție:

The registry key bypasses the error, and does not flag or fix the missing table header accessibility issue.

On Windows

  1. Quit the Acrobat application.

  2. Open the registry editor -  go to Run (Windows menu + R), type regedit.exe in the Open field and click OK.

  3. In the registry editor, based on your installed version of the product, go to the version-specific location listed below, and modify or create the DWORD key IgnoreTableHeaderCheck,

    • Location for Acrobat (32-bit):
      HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Adobe\Adobe Acrobat\DC\FeatureState
    • Location for Acrobat (64-bit):
      HKEY_LOCAL_MACHINE\SOFTWARE\Adobe\Adobe Acrobat\DC\FeatureState
    Notă:
    • If IgnoreTableHeaderCheck value = 1, Accessibility Checker in Acrobat passes the incorrect table header and displays no error.
    • If IgnoreTableHeaderCheck value = 0, Accessibility Checker in Acrobat detects the incorrect table header and shows an error in the Accessibility check result.
  4. Close the registry editor.

On macOS

  1. Quit the Acrobat application.

  2. Navigate to the folder /Library/Application Support/Adobe/Acrobat/DC/Preferences/

  3. Open the com.adobe.Acrobat.FeatureState.plist file in any plist editor.

  4. Add or modify the IgnoreTableHeaderCheck (bool) entry in the com.adobe.Acrobat.FeatureState.plist file:

    • If IgnoreTableHeaderCheck(bool) value = True, Accessibility Checker in Acrobat passes the incorrect table header and displays no error.
    • If IgnoreTableHeaderCheck(bool) value = False, Accessibility Checker in Acrobat detects the incorrect table header and shows an error in the Accessibility check result.
  5. Close the plist file.
