Description

Accoring to WCAG 2 validator, there is Empty table header error.

What does the Empty Table Header error mean?

An empty table header error means that one of the table headers on your post or page does not contain any text. This means that the <th> element is present but looks like this <th></th> with nothing between the opening and closing tags.

How to Fix It

If the table cell is a header, provide text within the cell that describes the column or row. If the cell is not a header or must remain empty (such as the top-left cell in a data table), make the cell a <td> rather than a <th>.

So, if <th></th> is empty, I render it as <td></td> (styling kept the same).
