 10 * Smarty {html_table} function plugin
 11 *
 12 * Type:     function<br>
 13 * Name:     html_table<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}
 38 * </pre>
