Alternatingly shading rows with @{}

Question

I want to alternately shade the rows in my table. I am aware of How to alternately shade rows in a table and similar questions. However, as my table is long and needs to be aligned very neatly in order to not be totally confusion, I make heavy use of the self-defined delimiters for cells via @{}. The formatting gets totally screwed when I try the solutions proposed elsewhere. I suppose the @{} is what trips up \rowcolors. How can I color the rows without screwing up the formatting?

A minimal example with my table is

\documentclass[a4paper]{scrartcl}

\usepackage{booktabs}
\usepackage[table]{xcolor}

\begin{document}

\rowcolors{2}{white}{gray!15} % <--- this is the solution from the other questions

\begin{center}
\begin{tabular}    {cl@{}r@{\,}r@{\,}r@{\,}r@{\,}r@{}l@{\qquad}l@{}r@{\,}r@{\,}r@{\,}r@{}lc@{\qquad}l@{}r@{\,}r@{)(}r@{}llc}

Here's something that might work for you. It uses the package pgffor. I've only partially implemented it: there's a lot to rewrite in your code. But I think it achieves the effect that you want.

\documentclass[a4paper]{scrartcl}

\usepackage{booktabs}
\usepackage[table]{xcolor}
\usepackage{pgffor}

\newcommand{\nnkweights}[1]{(\foreach \x in {#1} {\makebox[1.15em][r]{\x}})}
\begin{document}

\rowcolors{2}{white}{gray!15} % <--- this is the solution from the other questions

\begin{center}
\begin{tabular}    {c c  c  l c  c  c} \toprule
      & {\(SO(10)\) }  & \multicolumn{2}{c}{\(SU(5)\)}    & \multicolumn{2}{c}{\(\mathcal G_\mathrm{SM}\)} &          \\\cmidrule(rl){3-4}\cmidrule(rl){5-6}
Level & {weight}       & {weight}    & \(\mathrm{IR}_x\)  & {weight} & \(\mathrm{IR}_Y\)                   & SM state \\ \midrule
0 & \nnkweights{  0, 0, 0, 0, 1}  & \nnkweights{ 0, 1, 0, 0}  & \(\mathbf{10}_1\)             & \nnkweights{ 1, 0}\nnkweights{  1} & \(\mathbf{3} \times \mathbf{2}_\frac{1}{6}\)              & \(u_l\)  \\
1 & \nnkweights{  0, 0, 1, 0,-1}  & \nnkweights{ 0, 0, 0, 1}  & \(\overline{\mathbf 5}_{-3}\) & \nnkweights{ 0, 1}\nnkweights{  0} & \(\overline{\mathbf{3}} \times \mathbf 1_\frac{1}{3}\)    & \(d^c_r\)\\
2 & \nnkweights{  0, 1, -1, 1, 0} & \nnkweights{ 1, -1, 1, 0} & \(\mathbf{10}_1\)             & \nnkweights{ 0, 1}\nnkweights{  0} & \(\overline{\mathbf{3}} \times \mathbf 1_{-\frac{2}{3}}\) & \(u^c_r\)\\
3 & \nnkweights{  1, -1, 0, 1, 0} & \nnkweights{ 0, 0, 1,-1}  & \(\overline{\mathbf 5}_{-3}\) & \nnkweights{ 0, 0}\nnkweights{  1} & \(\mathbf{1} \times \mathbf 2_{-\frac{1}{2}}\)            & \(\nu_l\)\\
3 & \nnkweights{  0, 1, 0, -1, 0} & \nnkweights{ 1, 0, -1, 1} & \(\mathbf{10}_1\)             & \nnkweights{ 1, 0}\nnkweights{ -1} & \(\mathbf{3} \times \mathbf{2}_{\frac{1}{6}}\)            & \(d_l\)  \\
\bottomrule
\end{tabular}
\end{center}

\end{document}

I'm made a few additional changes: I got rid of the \qquads and I've added some \cmidrules. I might suggest putting the content of the \makeboxes in math-mode so that the negative sign is type-set correctly, but I've not implemented that change.

Regarding \qquad, if you really want the extra space in your document, I would suggest adding a dummy column and adding the appropriate white space via \rule{<dim>}{0pt} in its first occurrence. If you're particularly finicky about the space then you can do something like \rule{\dimexpr<desired-dimension>-2\tabcolsep\relax}{0pt}. Otherwise, the alternate row shading apparently doesn't like handling @{<detail>}.

Finally, I would suggest changing

\rowcolors{2}{white}{gray!15}

to

\rowcolors{5}{white}{gray!15}

to get the coloring out of your header. The row specification seems a bit off, but that's because the \cmidrules are fooling xcolor into thinking there are extra rows added to the table.

Having done this, the result will be
