PrettyDataFrames.jl

Provides a wrapper for a DataFrame object that gives better control over how each column is displayed.

Installation

using Pkg
pkg"add https://github.com/GHTaarn/PrettyDataFrames.jl"

Use

The only exported symbol is the PrettyDataFrame type which wraps a DataFrame object, e.g.

using DataFrames, PrettyDataFrames

x=PrettyDataFrame(DataFrame(a=rand(6), b=rand(6), c=1:6), :a => "%e", :b => "%9.1f")
filter!(:c => >(2), x.df)
display(x)

This would display the a and b columns using respectively the %e and %9.1f Printf format specifiers.
