-HTML Table Class
-################
-
-The Table Class provides functions that enable you to auto-generate HTML
-tables from arrays or database result sets.
-
-.. contents::
-  :local:
-
-.. raw:: html
-
-  <div class="custom-index container"></div>
-
-*********************
-Using the Table Class
-*********************
-
-Initializing the Class
-======================
-
-Like most other classes in CodeIgniter, the Table class is initialized
-in your controller using the ``$this->load->library()`` method::
-
-	$this->load->library('table');
-
-Once loaded, the Table library object will be available using::
-
-	$this->table
-
-Examples
-========
-
-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 ``set_heading()``
-method described in the function reference below).
-
-::
-
-	$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);
-
-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 ``set_heading()``
-method described in the class reference below).
-
-::
-
-	$this->load->library('table');
-
-	$query = $this->db->query('SELECT * FROM my_table');
-
-	echo $this->table->generate($query);
-
-Here is an example showing how you might create a table using discrete
-parameters::
-
-	$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();
-
-Here is the same example, except instead of individual parameters,
-arrays are used::
-
-	$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();
-
-Changing the Look of Your Table
-===============================
-
-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::
-
-	$template = array(
-		'table_open'		=> '<table border="0" cellpadding="4" cellspacing="0">',
-
-		'thead_open'		=> '<thead>',
-		'thead_close'		=> '</thead>',
-
-		'heading_row_start'	=> '<tr>',
-		'heading_row_end'	=> '</tr>',
-		'heading_cell_start'	=> '<th>',
-		'heading_cell_end'	=> '</th>',
-
-		'tbody_open'		=> '<tbody>',
-		'tbody_close'		=> '</tbody>',
-
-		'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>'
-	);
-
-	$this->table->set_template($template);
-
-.. note:: 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.
-
-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::
-
-	$template = array(
-		'table_open' => '<table border="1" cellpadding="2" cellspacing="1" class="mytable">'
-	);
-
-	$this->table->set_template($template);
-	
-You can also set defaults for these in a config file.

-***************
-Class Reference
-***************
-
-.. php:class:: CI_Table
-
-	.. attribute:: $function = NULL
-
-		Allows you to specify a native PHP function or a valid function array object to be applied to all cell data.
-		::
-
-			$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 $this->table->generate();
-
-		In the above example, all cell data would be ran through PHP's :php:func:`htmlspecialchars()` function, resulting in::
-
-			<td>Fred</td><td>&lt;strong&gt;Blue&lt;/strong&gt;</td><td>Small</td>
-
-	.. php:method:: generate([$table_data = NULL])
-
-		:param	mixed	$table_data: Data to populate the table rows with
-		:returns:	HTML table
-		:rtype:	string
-
-		Returns a string containing the generated table. Accepts an optional parameter which can be an array or a database result object.
-
-	.. php:method:: set_caption($caption)
-
-		:param	string	$caption: Table caption
-		:returns:	CI_Table instance (method chaining)
-		:rtype:	CI_Table
-
-		Permits you to add a caption to the table.
-		::
-
-			$this->table->set_caption('Colors');
-
-	.. php:method:: set_heading([$args = array()[, ...]])
-
-		:param	mixed	$args: An array or multiple strings containing the table column titles
-		:returns:	CI_Table instance (method chaining)
-		:rtype:	CI_Table
-
-		Permits you to set the table heading. You can submit an array or discrete params::
-
-			$this->table->set_heading('Name', 'Color', 'Size');
-
-			$this->table->set_heading(array('Name', 'Color', 'Size'));
-
-	.. php:method:: add_row([$args = array()[, ...]])
-
-		:param	mixed	$args: An array or multiple strings containing the row values
-		:returns:	CI_Table instance (method chaining)
-		:rtype:	CI_Table
-
-		Permits you to add a row to your table. You can submit an array or discrete params::
-
-			$this->table->add_row('Blue', 'Red', 'Green');
-
-			$this->table->add_row(array('Blue', 'Red', 'Green'));
-
-		If you would like to set an individual cell's tag attributes, you can use an associative array for that cell.
-		The associative key **data** defines the cell's data. Any other key => val pairs are added as key='val' attributes to the tag::
-
-			$cell = array('data' => 'Blue', 'class' => 'highlight', 'colspan' => 2);
-			$this->table->add_row($cell, 'Red', 'Green');
-
-			// generates
-			// <td class='highlight' colspan='2'>Blue</td><td>Red</td><td>Green</td>
-
-	.. php:method:: make_columns([$array = array()[, $col_limit = 0]])
-
-		:param	array	$array: An array containing multiple rows' data
-		:param	int	$col_limit: Count of columns in the table
-		:returns:	An array of HTML table columns
-		:rtype:	array
-
-		This method takes a one-dimensional array as input and creates a multi-dimensional array with a depth equal to the number of columns desired.
-		This allows a single array with many elements to be displayed in a table that has a fixed column count. Consider this example::
-
-			$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);
-
-			// Generates a table with this prototype
-
-			<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>
-
-
-	.. php:method:: set_template($template)
-
-		:param	array	$template: An associative array containing template values
-		:returns:	TRUE on success, FALSE on failure
-		:rtype:	bool
-
-		Permits you to set your template. You can submit a full or partial template.
-		::
-
-			$template = array(
-				'table_open'  => '<table border="1" cellpadding="2" cellspacing="1" class="mytable">'
-			);
-		
-			$this->table->set_template($template);
-
-	.. php:method:: set_empty($value)
-
-		:param	mixed	$value: Value to put in empty cells
-		:returns:	CI_Table instance (method chaining)
-		:rtype:	CI_Table
-
-		Lets you set a default value for use in any table cells that are empty.
-		You might, for example, set a non-breaking space::
-
-			$this->table->set_empty("&nbsp;");
-
-	.. php:method:: clear()
-
-		:returns:	CI_Table instance (method chaining)
-		:rtype:	CI_Table
-
-		Lets you clear the table heading and row data. If you need to show multiple tables with different data you should to call this method
-		after each table has been generated to clear the previous table information. Example::
-
-			$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();
