pt-show-grant doesn't support column-level grants

[In:<strong class="program">pt-show-grants</strong>]

Good day,

show-grant outputs incorrect Sql format when access to the table is on selected fields only.

consider the ff. table
Code: [Select all] [Show/ hide]
CREATE TABLE IF NOT EXISTS `table3` (
  `SOrNum` mediumint(9) unsigned NOT NULL auto_increment,
  `SPNum` mediumint(9) unsigned NOT NULL,
  `DateCreated` timestamp NOT NULL default CURRENT_TIMESTAMP,
  `DateRelease` timestamp NOT NULL default '0000-00-00 00:00:00',
  `ActualReleasedDate` timestamp NULL default NULL,
  `PckPrice` decimal(10,2) NOT NULL default '0.00',
  `Status` varchar(20) NOT NULL,
  `PaymentStat` varchar(20) NOT NULL default 'Unpaid',
  `CusCode` int(9) unsigned NOT NULL,
  `SANumber` mediumint(9) unsigned NOT NULL default '0',
  `SpecialInstruction` varchar(500) default NULL,
  PRIMARY KEY (`SOrNum`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;

if the user have only access to the following fields: DateCreated, PckPrice, PaymentStat, SANumber
the ouput of
Code: [Select all] [Show/ hide]
pt-show-grants --user=root --ask-pass --only=user

is the ff. which is invalid
GRANT DateCreated, PaymentStat, PckPrice), SELECT (SANumber ON `inventory`.`table3` TO 'user'@'%';
