 * "int unsigned", or both "int(11)" and "int" and so on.
 * The same applies to the other integer data types "tinyint",
 * "smallint", "mediumint" and "bigint".
 *
 * @param   string  $type1  the column type
 * @param   string  $type2  the column attributes
 *
 * @return  string  The original or changed column type.
