<h1>HTML Table Class</h1>

<p>The Table Class provides functions that enable you to auto-generate HTML tables from arrays or database result sets.</p>

<h2>Initializing the Class</h2>

<p>Like most other classes in Code Igniter, the Table class is initialized in your controller using the <dfn>$this->load->library</dfn> function:</p>

<code>$this->load->library('table');</code>
<p>Once loaded, the Table library object will be available using: <dfn>$this->table</dfn></p>


<h2>Examples</h2>

<p>Here is an example showing how you can create a table from a multi-dimensional array. 
Note that the first array index will become the table heading (or you can set your own headings using the 
<dfn>set_heading()</dfn> function described in the function reference below).</p>

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

<p>Here is an example of a table created from a database query result. The table class will automatically generate the 
headings based on the table names (or you can set your own headings using the <dfn>set_heading()</dfn> function described
in the function reference below).</p>

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


<p>Here is an example showing how you might create a table using discreet parameters:</p>

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

<p>Here is the same example, except instead of individual parameters, arrays are used:

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


<h2>Changing the Look of Your Table</h2>

<p>The Table Class permits you to set a table template with which you can specify the design of your layout.  Here is the template
prototype:</p>

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

<br />
$this->table->set_template($tmpl);
</code>

<p class="important"><strong>Note:</strong>&nbsp; You'll notice there are two sets of "row" blocks in the template.  These permit you to create alternating row colors or design elements that alternate with each 
iteration of the row data.</p>

<p>You are NOT required to submit a complete template.  If you only need to change parts of the layout you can simply submit those elements.
In this example, only the table opening tag is being changed:</p>

<code>
$tmpl =  array ( 'table_open'&nbsp;&nbsp;=> '&lt;table border="1" cellpadding="2" cellspacing="1" class="mytable">' );<br />

<br />
$this->table->set_template($tmpl);
</code>

<br />
<h1>Function Reference</h1>

<h2>$this->table->generate()</h2>
<p>Returns a string containing the generated table.  Accepts an optional parameter which can be an array or a database result object.</p>

<h2>$this->table->set_heading()</h2>

<h2>$this->table->add_row()</h2>

<br />
$this->table->set_template($tmpl);
</code>
