Description:
------------
For some strange reason phpdotnet\phd\Package_PEAR_XHTML overrides methods for formatting table tags defined in phpdotnet\phd\Package_Generic_XHTML, for example:

    public function format_entry($open, $name, $attrs, $props)
    {
        if ($open) {
            if ($props['empty']) {
                return '<td></td>';
            }
            return '<td>';
        }
        return '</td>';
    }

Unlike code in parent class, this does not add any attributes whatsoever, so it is impossible to even do colspan and rowspan in PEAR manual.

Commenting out format_table(), format_entry() and format_th_entry() improves output a lot.

Test script:
---------------
<entry morerows="1">...</entry>

Expected result:
----------------
<td rowspan="2">...</td>

Actual result:
--------------
<td>...</td>
