Question

我想在CI表类生成的表中添加页脚行。有一些类可用于扩展表类并添加此功能。如果没有扩展表类，我宁愿使用本机功能。

是否可以在CI表类中使用？

Answer 1

我最终在桌子底下放了一个类似格式的div，以提供页脚行的错觉。希望将来表类将包含tfoot功能。

我知道扩展类会将此功能添加到CI表类。

Answer 2

这是一个老问题，但我遇到了同样的问题，这里是修改后的表库，允许表格页脚

我确实扩展了表类，我还默认将模板设置为使用jquery ui，与上面的例子不同，我不重新创建不需要更新的基本方法。

在应用程序/库中添加名为MY_table.php的文件

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class MY_Table extends CI_Table{
var $footer = array();

    parent::__construct();

没有必要扩展表库，你可以使用set_template函数，传递数组模板。
