Writing to latex: omitting column with row index

[davidzentlermunro]

Is it possible to write a dataframe to tex without including a column that just has the row numbers?

[nalimilan]

I don't think so. I think the purpose of the show method for LaTeX is to provide a default representation of a DataFrame in LaTeX displays, but not to support any customization options (which could make the function very complex and would better be implemented in a separate package).

This may be something Latexify.jl could be helpful for.

using DataFrames
using Latexify
df = DataFrame(A = 'x':'z', B = ["M", "F", "F"])
latexify(df; env=:table, latex=false)

outputs:

\begin{tabular}{cc}
A & B\\
x & M\\
y & F\\
z & F\\
\end{tabular}

I don't often use DataFrames myself, so I haven't spent much time on tweaking the interface between DataFrames and Latexify. But there is already some rudimentary support and it might be rather easy to improve it if anyone is interested.

Can this be closed?

Yes can be closed - I'm happily writing tables using both DataFrames package and write command.
