Who this affects

Screen reader users reading price, size or specification tables.

Why it matters

Without headers each value is read on its own, so users cannot tell which size, plan or feature a number belongs to.

How to fix it

Add <th> header cells with scope="col" or scope="row" so every data cell has a header.
