Format.jl formatters

[jariji]

I would like to use formatters with the Format.jl syntax because I prefer that Python format syntax to printf syntax. Could that be supported internally or with an extension?

Hi @jariji !

Since a formatter is any function that returns an object to be rendered, you can do the following:

julia> using PrettyTables, Format

julia> A = rand(5, 5);

julia> pretty_table(A; formatters = (v, i, j) -> pyfmt("<8.4f", v))
