  Algorithm:    

 * The behavior of WML Tables is not exactly like the behavior of CSS Tables.

 * Two issues in particular need to be addressed:

 * 1) Since the CSS Static Algorithm used in the Layout Manager

 *    calculates the dimensions of the table based on the head row, the table

 *    will contain only as many columns as there are in the first row.  In WML

 *    this information is passed in the "columns" attribute.  Here we pad the

 *    first row if it does not contain enough cells.

 * 2) in WML, any extra cells in a row are "aggregated" into the last cell.
