  2.  * Themeing function to render a form as a table.
  3.  *
  4.  * The $form array should contain the following:
  5.  * - $form['heading'], a form item of the default (markup) type (thus with
  6.  *   only #value set), containing an (optional) heading.
  7.  * - $form['header'], an array of form items of the default (markup) type
  8.  *   (thus with only #value set), containing the header fields
  9.  * - $form['rows'], an array of form items containing the rows. Each row is
  10.  *   again an array of form items.
  11.  * - $form['empty'], if this is set, then no table will be rendered. You may
  12.  *   want to put an "empty message" in here.
  13.  *
  14.  * When $form['empty'] is not set, a table will be rendered first. After that,
  15.  * all other form items will get rendered.
  16.  * If $form['empty'] is set, $form['header'] and $form['rows] will be deleted,
  17.  * and then all other form items will get rendered.
