How to add attributes to table rows?

i don't know if you can do it with add_row()

PHP Code:

$cell = array('data' => 'Blue', 'class' => 'highlight', 'colspan' => 2);
$this->table->add_row($cell, 'Red', 'Green'); 


this is for a cell, but try that

PHP Code:

$cell = array('data' => array('Red', 'Green', 'Blue'), 'class' => 'highlight');
$this->table->add_row($cell); 


maybe that work but personnaly, i don't use this lib.
