Column formatter property broken?

[AYColumbia]

I wanted to right align my cell header and the row values since they're numeric so I found that I can add formatter and assign a function. Doing so, however, does NOT fire the function at all. I added a console.log and never saw a thing in the Console of dev tools. Is formatter supposed to work?

For now, I'm working around this by using the two properties below after digging into the source code.

{ 
   key: "ARBalance",
   name: "AR Balance",
   sortable: true,
   renderHeaderCell: headerCellNumericRenderer,
   renderCell: cellNumericRenderer
}

When I had, for example, { ..., formatter: myFunction }, myFunction never gets called.
