Correct table tagging is essential for PDF accessibility. Screen readers depend on proper structure (<TR>, <TH>, <TD>) and attributes like scope to read tables accurately. With PDFix Desktop, you can quickly fix tables manually, validate them, and now even use AI-powered tools to automate the process.
1. Check Table Tags
- Open your PDF in PDFix Desktop.
- Run Validation from the Tags panel to identify table issues.
- Review the tag tree to see if rows, headers, and cells are structured correctly.
2. Fix Structure
- If headers are tagged as data (or vice versa), double-click the tag and change the type.
- Rearrange rows or cells with drag-and-drop.
- If a table is mistakenly tagged as a paragraph, delete the tag and re-tag as Table.
3. Add Scope Attributes
- In the Tag Attributes panel, right-click a
<TH>cell → Add Attribute → Scope. - Choose
row,column, orboth. - Apply the same scope to multiple headers at once for consistency.
4. Finalize & Validate
- Confirm that each table uses
<TR>rows with<TH>and<TD>cells. - Ensure headers and data cells align logically.
- Run Validation again — the table should now pass accessibility checks.
