Third is aligning text into two cells:

Comrades! The European war has been raging for more than eighteen months. And as each month, as each day of the war goes by, it becomes clearer and clearer to the masses of the workers that the Zimmerwald Manifesto expressed the truth when it declared that phrases about “defence of the fatherland” and the like are nothing but capitalist deception.

With markdown.
