通过页面的按钮可以动态的创建一个表格
>
行<input type="text" name="rownum" /><br />
列<input type="text" name="colnum" /><br />
<input type="button" value="创建表格" onclick="createTab()" /><br />
<input type="text" name="delrow" />
<input type="button" value="删除行" onclick="delRow()" />
<br />
<input type="text" name="delcol" />
<input type="button" value="删除列" onclick="delCol()" />
<br />
<br />
<div>
</div>
