 *

 * Type:     function

 * Name:     html_table

 * Date:     Feb 17, 2003

 * Purpose:  make an html table from an array of data

 * Input:

 *         - loop = array to loop through

 *         - cols = number of columns

 *         - rows = number of rows

 *         - table_attr = table attributes

 *         - tr_attr = table row attributes (arrays are cycled)

 *         - td_attr = table cell attributes (arrays are cycled)

 *         - trailpad = value to pad trailing cells with

 *         - vdir = vertical direction (default: "down", means top-to-bottom)

 *         - hdir = horizontal direction (default: "right", means left-to-right)

 *         - inner = inner loop (default "cols": print $loop line by line,

 *                   $loop will be printed column by column otherwise)

 *

 *

 * Examples:

 * 

 * {table loop=$data}

 * {table loop=$data cols=4 tr_attr='"bgcolor=red"'}

 * {table loop=$data cols=4 tr_attr=$colors}
