Table header cell has no associated subcells

What is the issue?

PDF/UA > Logical Structure > Structure Elements > Tables > Table header cell assignments > Table header cell has no associated subcells

What does it mean?

In a table, there are header cells (<TH>) that do not have associated data cells (<TD>).

Therefore programs like screen readers can not recognize the reference between header and data cells.

How to fix it?

  1. Double click on the error message to jump to the corresponding header cell. The header cell is now also selected in the task pane "Logical Structure Tree".
  2. In the case of a simple table: set the correct scope of the selected header cell in the task pane "Properties" - choose "Row", "Column" or "Both".
  3. If table header cells do not apply for a whole column or row, you have a complex table. In that case, you have to set the reference between header cells and data cells by using header IDs. For that purpose, use the table tool of axesPDF QuickFix.
