Sorting

You may sort the table on a single column, again by specifying the header value. Use sortBy for ascending order or sortByDescending for descending order. Use sortByNone to clear any sorting you have previously added.

prettyTable rows
|> withHeaders headers
|> sortByDescending "Appeared in"
|> printTable

// Output:
