empty-table-header

since the table headings text should be visible.

How Users Are Affected
Table headings are essential for the user to perceive and understand the table data. The column and row headings give context and meaning to the table data. If table headings do not contain discernible text, some users will find it hard or even impossible to understand the table data. The lack of text in the table headings mainly affects reader users, since it is also used to indicate when switching rows or columns.
