I would like to horizontally center the icon in the column “Data”:

I’ve got textAlign: center on my column:

And in the icon renderer function, I’m horizontally centering it with CSS:

Yet it is still left-aligned.
What else do I have to do so that the icon in the column is centered horizontally?
This is somewhat of a guess, because I don’t have anything to test.
I notice that
margin: 0 autoisn’t working to center the image.This leads me to think that you need
display: blockon the image – that should let yourmarginrule do what you expect.
