Feature Request: Export DataFrame to LaTeX

[jacobadenbaum]

This is a little tricky since each row needs an index. This can be solved by indexing by row number, but I think a lot of people who want this feature will not be happy with the row number showing up. So, this feature will need to come in two parts:

1. Convert DataFrame to IndexedTable
2. Update printing methods to allow the user to suppress printing the row index.

Neither of these is particularly hard. Just needs doing.

I just needed this feature (DataFrame -> LaTeX-Table) and came up with this method.
But I did not look too much into the package so there might be better implementations.

using DataFrames
import TexTables

function TexTables.regtable(df::DataFrames.DataFrame)
    colnames = names(df)
    cols = map(icol -> TexTables.TableCol(colnames[icol], collect(1:nrow(df)), df[!,colnames[icol]]), 1:ncol(df))
    TexTables.regtable(cols...)
end
to_tex(regtable(df)) # df is the DataFrame to export
