Error · td-headers-attr
Table cells pointing to the wrong header
Lighthouse / axe call it: Table cells that use the headers attribute must only refer to cells in the same table · Cells in a <table> element that use the [headers] attribute refer to an element id not found within the same table
Cells reference a header that doesn't exist, so the table is read out of order.
Who it leaves out: blind people (screen readers)
