We're not seeing the full headers of File Explorer in your image. You can make several changes when View is showing on the menu bar. One of them is Details which usually is all I need, another is in the Grouping/Group by section, I use None. There's more in Options.
EDIT: Keep in mind that in Details view you can click/double-click a column heading to change the lineup, Ascending or Descending, can also right-click to add or remove columns.
