Nested column-wise cell merging using multicolumn in a long table environment
TeX - LaTeX Asked by aimbotter21 on May 15, 2021
The following table is set up as can be seen below. I would like to combine duplicated values in column 1-3 by merging the table cells column-wise. However, as you can see the merging of cells is on a different level or spans a different number of cells in each considered column.
begin{longtable}[!htbp]{ |m{2cm} m{3.7cm} m{2cm} | m{1.8cm} m{1.8cm} m{1.8cm}| }

end{longtable}
I tried hours with stacking the multicolumn command on various levels but none gave me the desired output. To clarify, in column 1, I would like to have 3 stacked cells (IG, Non-IG, Def), in column 2 accordingly 7 stacked cells and in column 3 accordingly 9 cells. Somehow every method I tried, completely screwed up the table layout, merging row-wise and column-wise.
Would highly appreciate any pointers!

I guess, the following is closer to the expected output:
documentclass{article}
usepackage{geometry}
usepackage[dvipsnames]{xcolor}
usepackage{nicematrix}
NiceMatrixOptions{cell-space-limits = 0.5tabcolsep}
begin{document}
begin{table}
centering

Didn't know how to include a picture otherwise, so pls see below what I get with your solution so far. I managed to compile the table in a way that the merging of the cells column-wise looks like in your example, but somehow the column width is out of bounds. I tried manually adjusting them using the initial column types that allow specification of the column width in the table environment (p{2cm} and m{2cm}, but that didn't work.
After looking hours in the pkg documentation, I am not any further at a working solution. I would love your feedback on this follow-up question, if you have an idea. Thanks!
