| classDESC | string | A CSS class name for TH elements to define that sorting is currently descending. | '' |
| columnAttributes | array | Column cells attributes. This is an array of the form: array(fieldName => array(attribute => value, ...) ...) This option is only used by XML/HTML based drivers. | array() |
| convertEntities | bool | Whether or not to convert html entities. This calls htmlspecialchars(). | true |
| defaultCellValue | string | What value to put by default into empty cells. | null |
| defaultColumnValues | array | Per-column default cell value. This is an array of the form: array(fieldName => value, ...). | array() |
| emptyRowAttributes | array | An associative array containing the attributes for empty rows. | array() |
| encoding | string | The content encoding. If the mbstring extension is present the default value is set from mb_internal_encoding(), otherwise it is ISO-8859-1. | 'ISO-8859-1' |
| evenRowAttributes | array | An associative array containing each attribute of the even rows. | array() |
| excludeVars | array | Variables to be removed from the generated HTTP queries. | array() |
| extraVars | array | Variables to be added to the generated HTTP queries. | array() |

| headerAttributes | array | Attributes for the header row. This is an array of the form: array(attribute => value, ...) | array() |
| hideColumnLinks | array | By default sorting links are enabled on all columns. With this option it is possible to disable sorting links on specific columns. This is an array of the form: array(fieldName, ...). This option only affects drivers that support sorting. | array() |

| oddRowAttributes | array | An associative array containing each attribute of the odd rows. | array() |
| onMove | string | Name of a Javascript function to call on onclick/onsubmit events when the user is either paging or sorting the data. This function receives a single object argument of the form: { page: <page>, sort: [{field: <field>, direction: <direction>}, ...], data: <user_data> }. Remark: setting this option doesn't remove the href attribute, you should return false from your handler function to void it (eg: for AJAX, etc..). | null |
| onMoveData | string | User data passed in the "data" member of the object argument passed to onMove. No JSON serialization is performed, this is assigned as a raw string to the "data" attribute. It's up to you to add quotes, slashes, etc... | '' |
| selfPath | string | The complete path for sorting and paging links. | $_SERVER['PHP_SELF'] |
| sortIconASC | string | The icon to define that sorting is currently ascending. Can be text or HTML to define an image. | '' |

| sortingResetsPaging | bool | Whether sorting HTTP queries reset paging. | true |
Examples
Simple AJAX support using the Prototype framework
<?php
require_once 'PEAR.php';
require_once 'Structures/DataGrid.php';
$datagrid =& new Structures_DataGrid(10);
$options['dsn'] = 'mysql://username@localhost/mydatabase';
$datagrid->bind("SELECT * FROM mytable", $options);
// Set the javascript handler function for onclick events
$datagrid->setRendererOption('onMove', 'updateGrid', true);
if (isset($_GET['ajax'])) {
// Handle table AJAX requests
if ($_GET['ajax'] == 'table') {
$datagrid->render();
}
// Handle pager AJAX requests
if ($_GET['ajax'] == 'pager') {
$datagrid->render('Pager');
}
exit();
}
// No AJAX request, render the initial content..
