Is there any way to add a className to a column header?

Right now you have to use the customHeadRender method and override the header component of the cell. You can see an example here: https://github.com/gregnb/mui-datatables/blob/master/examples/customize-columns/index.js

However, there's a PR in for a setCellHeaderProps feature (#889). If that gets approved, you'd be able to do it by adding the following to the options of the column:

setCellHeaderProps: () => ({className: "whatever-you-want"})
