* 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}
