How to include skewed text in a table

Question

I would like to make a table like this one, in which the columns have skewed text (I use booktabs):

I tried to search everywhere, but couldn't find an answer. Any advice on this?

Answer 1

To allow diagonal overlapping of the rotated headers, it's best to encase the \rotatebox directives in \rlap directives.

\documentclass{article}
\usepackage{graphicx,booktabs,amssymb}
\newcommand\rot[1]{\rlap{\rotatebox{45}{#1}}}
\newcommand\OK{$\checkmark$}
\begin{document}
\begin{table}[h]
\setlength\tabcolsep{9pt} % default: 6pt
\centering
     \begin{tabular}{@{} *{7}{l} }
     Reference & \rot{Ownership} 
               & \rot{No Claim Without Burn} 
               & \rot{Doublespend Prevention}
               & \rot{Decentralized Finality}
               & \rot{Transfer Confirmation}
               & \rot{Implementation}\
     \midrule
     XCLAIM    & \OK & \OK &     & \OK &     & \OK \
     Metronome & \OK & \OK & \OK &     & \OK & \OK \
     Gazi      & \OK &     &                       \
     \bottomrule
     \end{tabular}
\end{table}
\end{document}
