+ * ChangeLog:
+ * <pre>
+ *            - 1.0 initial release
+ *            - 1.1 added support for +/- N syntax for begin
+ *              and end year values. (Monte)
+ *            - 1.2 added support for yyyy-mm-dd syntax for
+ *              time value. (Jan Rosier)
+ *            - 1.3 added support for choosing format for
+ *              month values (Gary Loescher)
+ *            - 1.3.1 added support for choosing format for
+ *              day values (Marcus Bointon)
+ *            - 1.3.2 support negative timestamps, force year
+ *              dropdown to include given date unless explicitly set (Monte)
+ *            - 1.3.4 fix behaviour of 0000-00-00 00:00:00 dates to match that
+ *              of 0000-00-00 dates (cybot, boots)
+ *            - 2.0 complete rewrite for performance,
+ *              added attributes month_names, *_id

+ * Smarty {html_table} function plugin
+ * Type:     function<br>
+ * Name:     html_table<br>
+ * Date:     Feb 17, 2003<br>
+ * Purpose:  make an html table from an array of data<br>
+ * Params:
+ * <pre>
+ * - loop       - array to loop through
+ * - cols       - number of columns, comma separated list of column names
+ *                or array of column names
+ * - rows       - number of rows
+ * - table_attr - table attributes
+ * - th_attr    - table heading attributes (arrays are cycled)
+ * - tr_attr    - table row attributes (arrays are cycled)
+ * - td_attr    - table cell attributes (arrays are cycled)
+ * - trailpad   - value to pad trailing cells with
+ * - caption    - text for caption element
+ * - 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,
+ *                $loop will be printed column by column otherwise)
+ * </pre>
+ * Examples:
+ * <pre>
+ * {table loop=$data}
+ * {table loop=$data cols=4 tr_attr='"bgcolor=red"'}
+ * {table loop=$data cols="first,second,third" tr_attr=$colors}
+ * </pre>
