Examples

Table

With C# + Spectre.Console:

table.AddColumn("Foo");
table.AddColumn(new TableColumn("Bar").Centered());
table.AddRow("Baz", "[green]Qux[/]");
table.AddRow(new Markup("[blue]Corgi[/]"), new Panel("Waldo"));
AnsiConsole.Write(table);

With F# + FsSpectre:

table {
    column_text ""
    column (tableColumn { header_text "Feature"; centerd })
    row_text [| "Baz"; "[green]Qux[/]" |]
    row [| markup { text "[blue]Corgi[/]" }; panel { content "Waldo" } |]
} |> AnsiConsole.Write

Bar Chart

With C# + Spectre.Console:

AnsiConsole.Write(new BarChart()
    .Width(60)
    .Label("[green bold underline]Number of fruits[/]")
    .CenterLabel()
    .AddItem("Apple", 12, Color.Yellow)
    .AddItem("Orange", 54, Color.Green)
    .AddItem("Banana", 33, Color.Red));
