            Name = "Stanley"
            Age = 32
            Height = 175
        }
        {
            Name = "Akira"
            Age = 27
            Height = 175
        }
        {
            Name = "Andrei"
            Age = 35
            Height = 200
        }
    ]

typedList |> Printer.print

 Age      Height   Name     
 <Int32>  <Int32>  <String> 
 32       175      Stanley  
 27       175      Akira    
 35       200      Andrei

Selecting Columns

You can select which fields of your type to display as columns.

typedList
|> Printer
|> Printer.withColumns [ "Name"; "Height" ]
|> Printer.print

 Name      Height  
 <String>  <Int32> 
 Stanley   175     
 Akira     175     
 Andrei    200 

Ordering columns

Similarly you can also determine the order of fields to display.

typedList
|> Printer
|> Printer.withColumns [ "Name"; "Age"; "Height" ]
|> Printer.print

 Name      Age      Height  
 <String>  <Int32>  <Int32> 
 Stanley   32       175     
 Akira     27       175     
 Andrei    35       200 

Anonymous Records

open System

let anonRecords =
    [|
        for i in 1. .. 10. ->
            {|
                Number = i
                IsEven = i % 2. = 0.
                Log = Math.Log i
            |}
    |]


anonRecords
