I am trying to figure something out that I can't find the answer to.

I am trying to create a table where some cells in a row need to have multiple rows. I thought "multirow" would allow me to do this, which it does, but it incorrectly vertically centers the data that spans multiple rows. See the attached figure - it ends up being too high.

I realize that in the example I sent, I can just use 3 rows with the top and bottom being empty but in the case of having an even number of split rows, that method isn't possible. I also looked at the documentation for multirow and they specify that there is a finetuning parameter where you can adjust its height manually. I do not want to do this because if I am off even by a little bit it won't line up. Plus I figured there would be a better way.

Here is a MWE

documentclass[12pt,a4paper,twoside]{report}

%usepackage[latin1]{inputenc} % shouldn't you be using 'utf8'?

usepackage{amsmath}

%%%usepackage{amsfonts} % is loaded automatically by 'amssymb'

usepackage{array}

newcolumntype{M}[1]{>{centeringarraybackslash}m{#1textwidth}}



setlength{textheight}{9in} % Height of the main body of the text

setlength{topmargin}{-.5in} % .5" margin on top of page

setlength{headsep}{.5in}  % space between header and top of body

addtolength{headsep}{-headheight} % See The LaTeX Companion, p 85

setlength{footskip}{.5in}  % space between footer and bottom of body

setlength{textwidth}{6.25in} % width of the body of the text

setlength{oddsidemargin}{.25in} % 1.25" margin on the left for odd pages

setlength{evensidemargin}{0in} % 1.25"  margin on the right for even pages



% Marginal notes

setlength{marginparwidth}{.75in} % width of marginal notes

setlength{marginparsep}{.125in} % space between marginal notes and text
