  12   * Type:     function<br>
  13   * Name:     html_table<br>
  14   * Date:     Feb 17, 2003<br>
  15   * Purpose:  make an html table from an array of data<br>
  16   * Input:<br>
  17   *         - loop = array to loop through
  18   *         - cols = number of columns, comma separated list of column names
  19   *                  or array of column names
  20   *         - rows = number of rows
  21   *         - table_attr = table attributes
  22   *         - th_attr = table heading attributes (arrays are cycled)
  23   *         - tr_attr = table row attributes (arrays are cycled)
  24   *         - td_attr = table cell attributes (arrays are cycled)
  25   *         - trailpad = value to pad trailing cells with
  26   *         - caption = text for caption element 
  27   *         - vdir = vertical direction (default: "down", means top-to-bottom)
  28   *         - hdir = horizontal direction (default: "right", means left-to-right)
  29   *         - inner = inner loop (default "cols": print $loop line by line,
  30   *                   $loop will be printed column by column otherwise)
  31   *
  32   *
  33   * Examples:
  34   * <pre>
  35   * {table loop=$data}
  36   * {table loop=$data cols=4 tr_attr='"bgcolor=red"'}
  37   * {table loop=$data cols="first,second,third" tr_attr=$colors}
