Not fixed automatically structure, table

What veraPDF reports

TD does not contain Headers attribute, and Headers for this table cell cannot be determined algorithmically

veraPDF rule 7.5-1 = ISO 14289-1:2014 clause 7.5, test 1, checked on PDF object SETD.

In Adobe Acrobat’s Accessibility Checker the closest item is “Headers”.

What the requirement says

If the table's structure is not determinable via Headers and IDs, then structure elements of type TH shall have a Scope attribute

Can it be fixed automatically?

How to fix it by hand

Table tags are fixed in the structure tree: mark header rows/cells in the authoring application before export (e.g. “repeat as header row” in Word), or correct the table tags and header cells in a PDF editor's tag tree / table editor.
