A Problem with multicolumn

Question

I've got a problem with multicolumn. I have a big table and when I use the command as below I get the following error:

Misplaced \omit. \multispan ->\omit   \@multispan l.468 \end{tabular}}

I have reported below the only line in which if I delete the \multicolumn{1}{l}{\textbf{ADCS}} and replace it with only \textbf{ADCS} everything works.

I have other lines that have the same format of this one and they don't give me any mistake ( like the one below \multicolumn{1}{l}{\textbf{Payload}} & & & \textbf{5} & \textbf{20} & \textbf{1} & \textbf{6} \\ )

Do you have any idea why it does so?

\begin{table}[h!] 
\resizebox{\textwidth}{!}{% 
\centering \begin{tabular}{r c c c c c r} 
     \midrule 
     \multicolumn{1}{l}{\textbf{ADCS}} & & & \textbf{2.278} & \textbf{5} & 
    \textbf{0.114} & \textbf{2.392} \\ 
\midrule 
    \midrule
    \multicolumn{1}{l}{\textbf{Payload}} &  &  & \textbf{5} & \textbf{20} & \textbf{1} & \textbf{6} \\   
    \midrule     
\end{tabular}}
 \caption{\label{tab:list_equipment} List of equipment} 
\end{table}

Welcome to TeX.SE. It would be helpful if you composed a fully compilable minimal working example (MWE) including \documentclass and the appropriate packages that sets up the problem. While solving problems can be fun, setting them up is not. Then, those trying to help can simply cut and paste your MWE and get started on solving the problem. — samcarter_is_at_topanswers.xyz, Jun 19 '18 at 09:16

it is not clear if the answer of user165329 is real answer or is actually part of question. anyway, this table can be formatted (to my taste, of course) on better way:

\documentclass[a4paper,11pt]{report}
\usepackage{booktabs, makecell}
\renewcommand\theadfont{\bfseries\footnotesize}
\renewcommand\theadgape{}
\newcommand{\mcl}[1]{\multicolumn{1}{l}{\textbf{#1}}}
\usepackage{siunitx}
\usepackage{etoolbox}
\newrobustcmd{\B}{\bfseries}

\renewcommand*\ShowFrameColor{\color{red}}

Hum. Nothing Minimal in your preamble. Not really a Working example either. A MWE could look like

\documentclass[12pt]{article}
\usepackage[a4paper]{geometry}
\usepackage{booktabs,tabularx,multirow}
\begin{document}
\begin{tabular}{r c c c c c r}
\toprule
\multicolumn{1}{l}{\textbf{ADCS}} & & & \textbf{2.278} & \textbf{5} & \textbf{0.114} & \textbf{2.392} \\
\midrule
\multicolumn{1}{l}{\textbf{Payload}} &  &  & \textbf{5} & \textbf{20} & \textbf{1} & \textbf{6} \\
\bottomrule
\end{tabular}
\end{document}

which compiles fine.
