  16   * Input:<br>
  17   *         - loop = array to loop through
  18   *         - cols = number of columns
  19   *         - rows = number of rows
  20   *         - table_attr = table attributes
  21   *         - tr_attr = table row attributes (arrays are cycled)
  22   *         - td_attr = table cell attributes (arrays are cycled)
  23   *         - trailpad = value to pad trailing cells with
  24   *         - vdir = vertical direction (default: "down", means top-to-bottom)
  25   *         - hdir = horizontal direction (default: "right", means left-to-right)
  26   *         - inner = inner loop (default "cols": print $loop line by line,
  27   *                   $loop will be printed column by column otherwise)
  28   *
  29   *
  30   * Examples:
  31   * <pre>
  32   * {table loop=$data}
  33   * {table loop=$data cols=4 tr_attr='"bgcolor=red"'}
