Flip Tables
Because pretty-printing text tables in Java should be easy.

Development on this project has basically stopped. You can find a more comprehensive and actively-developed text table library at https://github.com/JakeWharton/picnic.
Usage
A FlipTable requires headers and data in string form:
String[] headers = { "Test", "Header" };
String[][] data = {
{ "Foo", "Bar" },
{ "Kit", "Kat" },
};
System.out.println(FlipTable.of(headers, data));โโโโโโโโคโโโโโโโโโ
โ Test โ Header โ
โ โโโโโโโชโโโโโโโโโฃ
โ Foo โ Bar โ
โโโโโโโโผโโโโโโโโโข
โ Kit โ Kat โ
โโโโโโโโงโโโโโโโโโ
They can be empty:
String[] headers = { "Test", "Header" };
String[][] data = {};
System.out.println(FlipTable.of(headers, data));โโโโโโโโคโโโโโโโโโ
โ Test โ Header โ
โ โโโโโโโงโโโโโโโโโฃ
โ (empty) โ
โโโโโโโโโโโโโโโโโ
Newlines are supported:
String[] headers = { "One Two\nThree", "Four" };
String[][] data = { { "Five", "Six\nSeven Eight" } };
System.out.println(FlipTable.of(headers, data));โโโโโโโโโโโคโโโโโโโโโโโโโโ
โ One Two โ Four โ
โ Three โ โ

โ Five โ Six โ
โ โ Seven Eight โ
โโโโโโโโโโโงโโโโโโโโโโโโโโ
Which means tables can be nested:
String[] innerHeaders = { "One", "Two" };
String[][] innerData = { { "1", "2" } };
String inner = FlipTable.of(innerHeaders, innerData);
String[] headers = { "Left", "Right" };
String[][] data = { { inner, inner } };
System.out.println(FlipTable.of(headers, data));โโโโโโโโโโโโโโโโโคโโโโโโโโโโโโโโโโ

Helper methods convert from types like lists:
List<Person> people = Arrays.asList(new Person("Foo", "Bar"), new Person("Kit", "Kat"));
System.out.println(FlipTableConverters.fromIterable(people, Person.class));โโโโโโโโโโโโโคโโโโโโโโโโโ

Or a database result:
ResultSet resultSet = statement.executeQuery("SELECT first_name, last_name FROM users");
System.out.println(FlipTableConverters.fromResultSet(resultSet));โโโโโโโโโโโโโโคโโโโโโโโโโโโ

Arbitrary objects are also supported:
String[] headers = { "First Name", "Last Name", "Age", "Type" };
Object[][] data = {
{ "Big", "Bird", 16, PersonType.COSTUME },
{ "Joe", "Smith", 42, PersonType.HUMAN },
{ "Oscar", "Grouchant", 8, PersonType.PUPPET }
};
