How to hide the types line when pretty printing a data frame

I’m sure this was mentioned before, I just can’t find it in PrettyTables.jl’s documentation nor here on Discourse. How can I hide the row indicating the columns’ types when printing a DataFrame?

julia> using DataFrames, PrettyTables

julia> n = 5

julia> df = DataFrame(x = rand(n), y = rand(Int, n))
5×2 DataFrame

Is this what you want? If so, it’s in the documentation under Keywords:

julia> pretty_table(df, nosubheader=true)
┌─────────────────────┬───────────────────────┐
│                   x │                     y │

Thanks. I didn’t even try

help?> pretty_table

just looked at the hosted documents. But of course, it’s there too… Thanks!

All kwargs are also accepted by show:

julia> show(DataFrame(rand(2,3), :auto), nosubheader=true)
2×3 DataFrame
 Row │ x1        x2        x3
─────┼──────────────────────────────
   1 │ 0.812423  0.815418  0.161294
   2 │ 0.834394  0.977342  0.327513

nosubheader was apparently deprecated Keyword arguments: change `noheader=true` -> `header=false` ? · Issue #160 · ronisbr/PrettyTables.jl · GitHub and replaced with show_subheader but I can’t find that replacement in the dev docs Search · Pretty Tables.

I have just copy-pasted the above.

Probably @Ronis_BR can guide us to a definite reference of currently supported kwargs.

8

BTW, why does show take the pretty_table kwargs?

9

show uses pretty_table under the hood, so it makes sense to forward the keyword arguments.

Hi @jar1 !

You can find the documentation about show_subheader here:

https://ronisbr.github.io/PrettyTables.jl/dev/man/usage/

Btw, I just realized that the docs ate wrong :slight_smile: I will fix it.
