Mixing booktabs and standard tabular commands

[jolars]

It seems like the output mixes \toprule and \bottomrule (booktab commands) with \hline (standard tabular command):

using TexTables
using RDatasets
       
neuro = RDatasets.dataset("boot", "neuro")
summarize(neuro) |> to_tex |> print

\begin{tabular}{r|ccccc}
\toprule
   & Obs & Mean     & Std. Dev. & Min      & Max      \\ \hline
V1 &  40 & -232.720 &    12.862 & -249.900 & -196.900 \\
V2 & 418 & -186.567 &    37.206 & -249.000 &  -98.600 \\
V3 & 469 &  -66.160 &    39.719 & -235.800 &   -0.100 \\
V4 & 468 &   48.074 &    30.760 &    1.000 &  197.800 \\
V5 & 445 &  162.483 &    38.111 &   75.600 &  249.300 \\
V6 &  90 &  229.740 &    18.718 &  154.300 &  249.700 \\
\bottomrule
\end{tabular}

Please consider changing \hline to \midrule (or \toprule and \bottomrule to \hline).

Good point! This is pretty easy to change, and I agree that in this example it looks better, but I'm nervous about just changing it globally for all the tables since I don't actually know whether or not it is perfectly drop-in interchangeable with \hline.

Perhaps an option in the to_tex function? Can always change the default to pure booktab at a later date.

Sounds good. Although I always use booktabs myself, perhaps the default really should be standard latex (only hline). Maybe the best approach would be to just have a booktabs = false argument in to_tex()?
