Table Accessibility for PDF/UA Compliance

The Reading Order Tool:To fix this error, use the Reading Order tool in Adobe Acrobat. Start by opening your document and navigating to ‘Prepare for Accessibility’. From there, access the Reading Order tool. This tool is crucial for manipulating how screen readers interpret the structure of your document, particularly tables.

Edit Table Properties: Once you’ve opened the Reading Order tool, right-click and select ‘Table Editor’. This allows you to directly edit the table properties. The next step is crucial: select all the cells in the top row of your table, right-click, and choose ‘Table Cell Properties’. Here, set the scope to ‘Column’. This action tells Acrobat that these cells are headers for the columns below.

Sett the Scope: Repeat a similar process for the row headers. Select the cells on the left side of your table, right-click, choose ‘Table Cell Properties’, and change the scope to ‘Row’. This step is vital for Acrobat to understand that these cells are headers for the rows to their right.

Testing and Saving: After adjusting these settings, save your file. Though we’ve made significant changes, it’s always good to retest your document to ensure the error is resolved. Testing is a crucial step in the process of making accessible documents.
