[ANN] PrettyTables.jl v1.2.2

Hi!

I just tag a new version of PrettyTables.jl (v1.2.2) and I would like to point out an amazing work done by @lorenzoh (GitHub, I am not sure if he is here in Discourse). He had an idea to use CustomTextCell so that we can have cells with ANSI escape sequences. Thus, we can now display anything inside a text cell composed of text and ANSI escape sequences (only those that change the decoration).

Hence, we can now create complex tables using PrettyTables to render tables inside cells:

julia> using PrettyTables

julia> sc1 = [7.4 73.5; 3.1 27.2; 2.5 15.6; 1.8 9.0];

julia> sc2 = [7.4 73.5; 3.1 27.2; 2.5 15.6; 1.8 9.0];

julia> case = ["< 5000", "5000 - 10000", "10000 - 15000", "> 15000"];

julia> str_sc1 = pretty_table(String, sc1, header = ["avg.", "max"], color = true, hlines = [:header], vlines = :none, newline_at_end = false, highlighters = hl_row(4, crayon"bold red"));
str
julia> str_sc2 = pretty_table(String, sc2, header = ["avg.", "max"], color = true, hlines = [:header], vlines = :none, newline_at_end = false, highlighters = hl_row(4, crayon"bold red"));

julia> str_case = pretty_table(String, case, header = [" "], color = true, hlines = [:header], vlines = :none, tf = tf_borderless, newline_at_end = false);

julia> table = [AnsiTextCell(str_case) AnsiTextCell(str_sc1) AnsiTextCell(str_sc2)];

We can also add plots inside the table cells using UnicodePlots:

julia> using PrettyTables, UnicodePlots

julia> str_pop = sprint(io -> show(io, barplot(
           ["", "", ""],
           [12.396, 6.748, 0.729]
       )), context = :color => true);

julia> str_idh = sprint(io -> show(io, barplot(
           ["", "", ""],
           [0.805, 0.799, 0.807]
       )), context = :color => true);

julia> table = ["\nSão Paulo\nRio de Janeiro\nSão José dos Campos" AnsiTextCell(str_pop) AnsiTextCell(str_idh)];

julia> pretty_table(table, header = ["", "Population (in mil.)", "IDH"], alignment = :l, header_alignment = :c, linebreaks = true, vlines = :none, hlines = [:header])

Holy Julia. I feel like I am living in a retro future of 1982 watching the output of my computer terminal.

Can it be used in Wave/Jupyter scripts to be rendered in an HTML/PDF document ?

Main motivation to implement this for me was to use as a plotting backend in FastAI.jl, so stay tuned for that :eyes: PR. Below shows an example of nested tables and using ImageInTerminal.jl to render images inside the cells:

Yes! But in this case you need to use the HTML backend which is not 100% stable yet.
