/**
 * Return a themed table.
 *
 * @param $header
 *   An array containing the table headers. Each element of the array can be
 *   either a localized string or an associative array with the following keys:
 *   - "data": The localized title of the table column.
 *   - "field": The database field represented in the table column (required if
 *     user is to be able to sort on this column).
 *   - "sort": A default sort order for this column ("asc" or "desc").
 *   - Any HTML attributes, such as "colspan", to apply to the column header cell.
 * @param $rows
 *   An array of table rows. Every row is an array of cells, or an associative
 *   array with the following keys:
 *   - "data": an array of cells
 *   - Any HTML attributes, such as "class", to apply to the table row.
 *
 *   Each cell can be either a string or an associative array with the following keys:
 *   - "data": The string to display in the table cell.
 *   - "header": Indicates this cell is a header.
 *   - Any HTML attributes, such as "colspan", to apply to the table cell.
 *
 *   Here's an example for $rows:
 *   @verbatim
 *   $rows = array(
 *     // Simple row
 *     array(
 *       'Cell 1', 'Cell 2', 'Cell 3'
 *     ),
 *     // Row with attributes on the row and some of its cells.
 *     array(
 *       'data' => array('Cell 1', array('data' => 'Cell 2', 'colspan' => 2)), 'class' => 'funky'
 *     )
 *   );
 *   @endverbatim
 *
 * @param $attributes
 *   An array of HTML attributes to apply to the table tag.
 * @param $caption
 *   A localized string to use for the <caption> tag.
 * @return
 *   An HTML string representing the table.
