Providing a reproducible result on the main branch for both escape=True and escape=False:

• escape=True:

  \begin{tabular}{ll}
  \toprule
  hello_world & hello \\
  \midrule
  0 & world \\
  \bottomrule
  \end{tabular}
  

• escape=False:

  \begin{tabular}{ll}
  \toprule
  hello_world & hello \\
  \midrule
  0 & world \\
  \bottomrule
  \end{tabular}

Thanks for the report! Agreed that column labels should also be escaped. I've also confirmed that index labels are escaped.

@rhshadrach Is this issue a duplicate of #57362? I noticed that PR #61307 has already been created to address it.

Indeed, thanks! Closing.
