 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

 31:  * </pre>
 32:  * Examples:
 33:  * <pre>
 34:  * {table loop=$data}
 35:  * {table loop=$data cols=4 tr_attr='"bgcolor=red"'}
