DataTable header not centered when sort arrows are present, and not reading \n new line character

My table headers are not fully centered due to the sort arrows, even though I included 'textAlign': 'center' in style_header (see how “Control Baseline” is not centered in the screenshot attached). Does anyone know how to fix this?

Separately, how could I make it so that the header reads a new line break? e.g. “Difference\n(T-C)” in the screenshot attached.
