[PHP]CodeIgniter学习手册（六）：HTML表格类

初始化类

$this->load->library('table');

一旦被加载,可以这样建立一个表格库对象的实例: $this->table

此例演示如何通过一个多维数组（multi-dimensional array）自动生成表格。

注意:数组的第一个索引将成为表头(或者你可以通过set_heading()函数自定义表头)。

$this->load->library('table');$data = array(             array('Name', 'Color', 'Size'),             array('Fred', 'Blue', 'Small'),             array('Mary', 'Red', 'Large'),             array('John', 'Green', 'Medium')             );echo $this->table->generate($data);

效果图：

下面是一个由数据库查询结构创建而成的表格例子。

表格类会基于表格的名字自动地生成表格标题(参考下面记述的函数，你可以使用set_heading()函数设置你自己的标题)。

$this->load->library('table');$query = $this->db->query("SELECT * FROM my_table");echo $this->table->generate($query);

效果截图：

$this->load->library('table');$this->table->set_heading('Name', 'Color', 'Size');$this->table->add_row('Fred', 'Blue', 'Small');$this->table->add_row('Mary', 'Red', 'Large');$this->table->add_row('John', 'Green', 'Medium');echo $this->table->generate();

$this->load->library('table');$this->table->set_heading(array('Name', 'Color', 'Size'));$this->table->add_row(array('Fred', 'Blue', 'Small'));$this->table->add_row(array('Mary', 'Red', 'Large'));$this->table->add_row(array('John', 'Green', 'Medium'));echo $this->table->generate();

$tmpl = array (                    'table_open'          => '<table border="0" cellpadding="4" cellspacing="0">',                    'heading_row_start'   => '<tr>',                    'heading_row_end'     => '</tr>',                    'heading_cell_start'  => '<th>',                    'heading_cell_end'    => '</th>',                    'row_start'           => '<tr>',                    'row_end'             => '</tr>',                    'cell_start'          => '<td>',                    'cell_end'            => '</td>',                    'row_alt_start'       => '<tr>',                    'row_alt_end'         => '</tr>',                    'cell_alt_start'      => '<td>',                    'cell_alt_end'        => '</td>',                    'table_close'         => '</table>'              );$this->table->set_template($tmpl);

$tmpl = array ( 'table_open'  => '<table border="1" cellpadding="2" cellspacing="1" class="mytable">' );$this->table->set_template($tmpl);

函数参考：

$this->table->set_caption()

$this->table->set_caption('Colors');

$this->table->set_heading('Name', 'Color', 'Size');$this->table->set_heading(array('Name', 'Color', 'Size'));

$this->table->add_row()

$this->table->add_row('Blue', 'Red', 'Green');$this->table->add_row(array('Blue', 'Red', 'Green'));

如果你想要单独设置一个单元格的属性，你可以使用一个关联数组。

关联键名 'data' 定义了这个单元格的数据。

其它的键值对 key => val 将会以 key='val' 的形式被添加为该单元格的属性:

$cell = array('data' => 'Blue', 'class' => 'highlight', 'colspan' => 2);$this->table->add_row($cell, 'Red', 'Green');// 生成// <td class='highlight' colspan='2'>Blue</td><td>Red</td><td>Green</td>

$this->table->make_columns()

$list = array('one', 'two', 'three', 'four', 'five', 'six', 'seven', 'eight', 'nine', 'ten', 'eleven', 'twelve');$new_list = $this->table->make_columns($list, 3);$this->table->generate($new_list);

<table border="0" cellpadding="4" cellspacing="0"><tr><td>one</td><td>two</td><td>three</td></tr><tr><td>four</td><td>five</td><td>six</td></tr><tr><td>seven</td><td>eight</td><td>nine</td></tr><tr><td>ten</td><td>eleven</td><td>twelve</td></tr></table>

$tmpl = array ( 'table_open'  => '<table border="1" cellpadding="2" cellspacing="1" class="mytable">' );$this->table->set_template($tmpl);$this->table->set_empty()

$this->table->set_empty(" ");$this->table->clear()

$this->load->library('table');$this->table->set_heading('Name', 'Color', 'Size');$this->table->add_row('Fred', 'Blue', 'Small');$this->table->add_row('Mary', 'Red', 'Large');$this->table->add_row('John', 'Green', 'Medium');echo $this->table->generate();$this->table->clear();$this->table->set_heading('Name', 'Day', 'Delivery');$this->table->add_row('Fred', 'Wednesday', 'Express');$this->table->add_row('Mary', 'Monday', 'Air');$this->table->add_row('John', 'Saturday', 'Overnight');echo $this->table->generate();$this->table->function

$this->load->library('table');$this->table->set_heading('Name', 'Color', 'Size');$this->table->add_row('Fred', '<strong>Blue</strong>', 'Small');$this->table->function = 'htmlspecialchars';echo $this->table->generate();

<td>Fred</td><td><strong>Blue</strong></td><td>Small</td>
