int[] empIds = { 1, 2, 3, 4, 5, 6, 7, 8, 9 };
String[] firstNames = { "Hari", "Ram", "Chamu", "Sowmya", "Harini", "Lahari", "Rama", "Lakshman", "Sandya" };
Table table = Table.create().addColumns(IntColumn.create("Employee Ids", empIds))
.addColumns(StringColumn.create("FirstName", firstNames));
System.out.println("First 3 rows : \n" + table.first(3));
