Structures_DataGrid: Columns for fields missing in first record?

Hi I encountered that if the records of the datasource do not have a unique set of fields, the columns are only taken from the first record: $data = array(

    array('name' => 'Mark', 'email' => 'mark@xyz.com', 'age' => '90'),
    array('name' => 'Helen', 'age' => '40'),

); $datagrid =& new Structures_DataGrid(); $datagrid->bind($data); $datagrid->render(DATAGRID_RENDER_CONSOLE); outputs: +-------+--------------+-----+

| name  | email        | age |

+-------+--------------+-----+ | Mark | mark@xyz.com | 90 |

| Helen |              | 40  |

+-------+--------------+-----+ If the source is changed to: $data = array(

    array('name' => 'Helen', 'age' => '40'),
    array('name' => 'Mark', 'email' => 'mark@xyz.com', 'age' => '90'),

); the email column is missing: +-------+-----+ | name | age | +-------+-----+ | Helen | 40 | | Mark | 90 | +-------+-----+ I did not find an option to change this behaviour; now I wonder if I missed something, or if this should be subject to a feature request, or if this kind of source structure is just not considered to be appropriate. Thanks Markus
