?自定義html視圖
eXtremeTable使用View接口來生成HTML。你可以使用發行包已經提供的視圖，或者你可以插入自己的視圖實現。如果要定義自己的視圖只需實現View接口，擴展AbstractHtmlView類便可。

?????? ??????? new MyToolbar(html, model).layout();
?????? ??? }
?????? ??? protected void statusBar(HtmlBuilder html, TableModel model) {
?????? ??????? new DefaultStatusBar(html, model).layout();
?????? ??? }
}
然后在<ec:table>中添加一個屬性view=”MyView的完整類名”，運行效果如下：
TableModel());
?????? ??? }
?????? ??? protected void toolbar(HtmlBuilder html, TableModel model) {
?????? ??????? new MyToolbar(html, model).layout();
?????? ??? }
?????? ??? protected void statusBar(HtmlBuilder html, TableModel model) {
?????? ??????? new DefaultStatusBar(html, model).layout();
?????? ??? }
}
然后在<ec:table>中添加一個屬性view=”MyView的完整類名”。
為表格添加操作在實際應用，特別是在一些管理系統中前臺頁面往往查看信息與編輯、刪除都放在一起。對于eXtremeTable達到這樣的效果只需在jsp文件中（自定義一列）如下：
<ec:column alias="操作" filterable="false" sortable="false" >
<a href="${pageContext.request.contextPath}/servlet/EmployeeServlet?param=edit&id=${employee.id}">編輯</a>
<!--使用圖片的好處就是可以避免國際化的問題-->
<a onclick="confirm('真的刪除');" ><img border="0" src ="${pageContext.request.contextPath}/images/delete.jpg"></a>
</ec:column>
