I haven't been able to tweak this by trying various available fonts through the built-in configuration option.
Please take a look at the attached image, my main font is WarpSans, and I use 'Courier New 10' as a substitue for 'Courier 18x12'.
It looks like a monospaced font is what the table display should use, but instead it's using something else, and whatever it's using, it's not controlled by the user adjustable settings.
Thanks!
