Thanks! This works (and also more or less tells me how it works, so I can fiddle with it).

I am trying to create a table in which each line starts one space later (i.e., it looks like the upper triangular part of a matrix). The first entry of each<br class="">
row is essentially the row number. The code in the first attachment yields a good version of this (see pdf in second attachment, but I would like<br class="">
to also create a grid of lines separating the entries. I can certainly put in horizontal lines using \hline, but how do I get vertical lines that line up<br class="">
in the columns (like I would get if I used a format {|c|c|c|c|}), but do not extend down into the rows where nothing is supposed to appear?<br class="">
