This post gives a convenient approach to generate Latex code and I am trying to reproduce that.



This is a piece of Python code,



>>> df = pd.DataFrame('name': ['Raphael', 'Donatello'],
... 'mask': ['red', 'purple'],
... 'weapon': ['sai', 'bo staff'])
>>> print(df.to_latex(index=False)) # doctest: +NORMALIZE_WHITESPACE


which generated this Latex code



begintabularlll
toprule
name & mask & weapon \
midrule
Raphael & red & sai \
Donatello & purple & bo staff \
bottomrule
endtabular


I compiled this code and got this table



enter image description here



and this error



Undefined control sequence

l.15 toprule

The control sequence at the end of the top line
of your error message was never def'ed. If you have
misspelled it (e.g., `hobx'), type `I' and the correct
spelling (e.g., `Ihbox'). Otherwise just continue,
and I'll forget about whatever was undefined.


How to fix it?

    toprule is defined in the booktabs package. Just include it in your document.

toprule (and midrule or bottomrule) are defined in the booktabs package. It must be included before any use.



This package largely improves the visual appearance of tables by providing rules with varying width and by fixing some line spacing problems. Standard latex uses hline to draw a rule between lines.
