如何将 tfoot 行添加到使用 codeigniter 表类生成的表中

Question

我想在 CI 表类生成的表中添加页脚行。有一些类可以扩展表类并添加此功能。如果可用，我更愿意使用本机功能而不扩展表类。

CI表类中可以吗？

Answer 1

我最终在表格下方放置了一个具有类似格式的 div，以提供页脚行的错觉。希望将来 table 类将包含 tfoot 功能。

我知道扩展类会将此功能添加到 CI 表类中。

Answer 2

这是一个老问题，但我刚刚遇到了同样的问题，这是修改后的表格库，允许表格页脚

Answer 3

我确实扩展了表格类，我还将模板设置为默认使用 jquery ui，并且与上面的示例不同，我不重新创建不需要更新的基本方法。

在应用程序/库中添加一个名为 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();
function __construct()
{
    parent::__construct();
    $this->template = array(
        'table_open'            => '<table class="ui-corner-top ui-widget" >',

        'thead_open'            => '<thead class="ui-widget-header">',
        'thead_close'           => '</thead>',
        'heading_row_start'     => '<tr>',
        'heading_row_end'       => '</tr>',

Answer 5

不需要扩展表库，你可以使用set_template函数，传递数组模板。
