how to create a table with acm

Question

I am creatin a table with latex using ACM template with \documentclass[sigconf, anonymous]{acmart} This is my code:

\begin{table}
\centering
\begin{tabulary}{\textwidth}{CLCL}
\toprule
\multicolumn{2}{c}{Security} & 
\multicolumn{2}{c}{Data protection} \\\cmidrule(rl){1-2}\cmidrule(rl){3-4}
Level & \hfil Mode & Encryption & \hfil Authenticity\\
%\midrule
\cmidrule(rl){1-1}\cmidrule(rl){2-2}\cmidrule(rl){3-3}\cmidrule(rl){4-4}
  0 & No Security     & No  &  Not validated   \\
  1 & AES-CBC-MAC-32  & No  &  32-bit MIC \\   
  2 & AES-CBC-MAC-64  & No  &  64-bit MIC   \\   
  3 & AES-CBC-MAC-128 & No  &  128-bit MIC  \\   
  4 & AES-CTR         & Yes &  Not validated       \\   
  5 & AES-CCM-32      & Yes &  32-bit MIC     \\   
  6 & AES-CCM-64      & Yes &  64-bit MIC     \\   
  7 & AES-CCM-128     & Yes &  128-bit MIC    \\
  \bottomrule
\end{tabulary}
\end{table}

Initially, with IEEE template I got:

but with the ACM, I got this:

If you get a TeX error then you should not even look at the PDF, look at the log, your log will show

! LaTeX Error: Environment tabulary undefined.

as tabulary is not defined. (You must have loaded booktabs though otherwise the output would not have the horizontal rules).

You need

\usepackage{tabulary}

\documentclass{article}
\usepackage{booktabs}
\begin{document}

\begin{table}
\centering
\begin{tabulary}{\textwidth}{CLCL}
\toprule
\multicolumn{2}{c}{Security} & 
\multicolumn{2}{c}{Data protection} \\\cmidrule(rl){1-2}\cmidrule(rl){3-4}
Level & \hfil Mode & Encryption & \hfil Authenticity\\
%\midrule
\cmidrule(rl){1-1}\cmidrule(rl){2-2}\cmidrule(rl){3-3}\cmidrule(rl){4-4}
  0 & No Security     & No  &  Not validated   \\
  1 & AES-CBC-MAC-32  & No  &  32-bit MIC \\   
  2 & AES-CBC-MAC-64  & No  &  64-bit MIC   \\

  \bottomrule
\end{tabulary}
\end{table}
