Now some use-case examples.  Suppose we want a table to have 10 rows


<table>
<tr><td>a</td></tr>
<tr><td>b</td></tr>
<tr><td>c</td></tr>
<tr><td>&nbsp;</td></tr>
<tr><td>&nbsp;</td></tr>
<tr><td>&nbsp;</td></tr>
<tr><td>&nbsp;</td></tr>
<tr><td>&nbsp;</td></tr>
<tr><td>&nbsp;</td></tr>
<tr><td>&nbsp;</td></tr>
</table>
