Wayne,
When you create a hole table the hole notes in the table are controlled by
the dimension style associated to each hole tag. By default the style
assigned to the hole tags will be the dimension style assigned to "Hole Tag"
in the active object defaults style. If you want to change that, create a
new dimension style with the hole notes formatted as you wish. Then edit
the object defaults style that is being used by your active standard style,
and set the object style next to "Hole Tag" to your newly defined dimension
style.
