columns() public method

This method expects asceding integer values as the keys, which map to the appropriate columns. Currently, there is no special "header" option, but you can define them for your own. Example Usage: $output = array( array('Name', 'Age'), array('----', '---'), ); foreach($users as $user) { $output[] = array($user->name, $user->age); } $this->columns($output); Would render something similar to: Name Age ---- --- Jane Doe 22 Foo Bar 18 This method also calculates the needed space between the columns. All option params given also get passed down to the out() method, which allow custom formatting. Passing something like $this->columns($output, array('style' => 'red) would print the table in red.
