Re: Help reproducing this matrix in TeXmacs

Apologies for not following up earlier. Giovanni, you are absolutely right.

To change the size and alignements, start by selecting cells, and then use the menu Format > Cell…
* (say,) Width / Minimum / 2cm 
* Alignment …

There are also shortcuts in the focus toolbar, see the Cell > Cell Properties… and the 4th one in this group.

You seen use these menus on the example I sent earlier to access my settings.

It might make sense to have a look at the general documentation on tables, in the Jolly Writer for instance.

Regards,
Basile.
