Large table cells have no headers
td-has-header
In a table big enough to need them, data cells are not connected to any header.
Who this affects
Screen reader users, who hear a stream of values with no idea which column each belongs to.
Fix it in WordPress
TablePress produces correct headers when the "first row is a header" option is enabled. Turn it on rather than styling the first row to look like a header.
What the fix is, technically
Add proper th elements with scope attributes, so every data cell has a header.
