Possible to remove "Sortability" icon on table headers?

[ethanard2]

I know it is possible to remove the "unsorted state" in a column, by setting enableSortingRemoval={false}

But the "unsorted state" icon still shows up by default for all other columns. Is there a way to disable that? I would prefer to just show nothing on those columns, and only have an arrow on the column which is sorted. I want them to be sortable, I just don't want that up/down arrow as it is distracting.
