Template talk:Hair space

A couple of questions
Is narrow no-break thinner than thin?

I notice narrow no-break and thin are both nonbreaking. But are they the same width? If so, why do they both exist?

Narrow no-break, 2 pixel and thin all look the same width. Is there a difference or differences, and if so what?

Do &amp;nbsp;, &amp;ensp; and &amp;emsp; also have –  templates? If not, why not? If so, why don't the template rather than the HTML forms appear in the table?
