Yii Booster - td cell height when contains progress bar

[snsnsns]

I'm creating app with Yii and YiiBooster. When I put a TbProgress widget into a \[code\]td\[/code\] cell - it's height seems to have some kind of bottom padding (like 20-30px). It looks pretty bad as it causes my table rows to be higher than they should.There was a \[code\]margin-bottom\[/code\] defined to \[code\]40px\[/code\] (in \[code\]bootstrap.css\[/code\] file) but I removed it - it is still to high.Anyone knows where can I change it?Here is my code: \[code\]$this->widget('bootstrap.widgets.TbGridView', array( 'id' => 'invite-grid', 'type' => 'striped condensed', 'dataProvider' => $dataProvider, 'columns' => array( 'idProject', 'name', array( 'header' => 'Post?p', 'value' => function($data) { Controller::widget('bootstrap.widgets.TbProgress', array( 'percent' => ($data->projectInvites +1 )/ $data->projectMaxInvites * 100, )); }, 'htmlOptions' => array ( 'style' => '' ), ), array( 'class' => 'bootstrap.widgets.TbButtonColumn' ) )));\[/code\]
