如何在Ajax Html编辑器中添加Html表？

如何在ajax html编辑器中添加html表。我已经在编辑器中成功编辑了字体和字体大小，但是当我尝试在编辑器中添加html表时，我碰到了一堵砖墙。

这里是一个示例代码代码，直到现在为止...不成功...

这是html：

how do i add html tables in ajax html editor. i ve successfully edited fonts and fonts size in the editor but i ve hit a brick wall when i tried adding html table in the editor.
here is a sample code code of how m doing till now.. unsuccessfully...
This is the html :

<HTMLEditor:Editor runat="server" Id="editor" Height="300px" AutoFocus="true" Width="675px" />
              <input type="button" value="Insert html table" onclick="insertTable();" />          

这是脚本：

and this is the script :

<script type="text/JavaScript">
    function insertTable() {
        var ee = $find("<%= editor.ClientID %>");
        var editPanel = ee.get_editPanel();
        var designMode = AjaxControlToolkit.HTMLEditor.ActiveModeType.Design;
        if (editPanel.get_activeMode() == designMode) {
            var designPanel = editPanel.get_modePanels()[designMode];
            designPanel.insertHTML("<table><tr><td></td></tr></table>");
        }
    }
</script>

任何人都可以告诉我做错了什么或如果完全错误的话。！

谢谢： - ）
