-<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 CodeIgniter, 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 discrete 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 $this->table->generate();
-</code>
-
-<p>Here is the same example, except instead of individual parameters, arrays are used:</p>
-
-<code>
-$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>$this->table->set_caption()</h2>
-
-<p>Permits you to add a caption to the table.</p>
-
-<code>$this->table->set_caption('Colors');</code>
-
-<h2>$this->table->set_heading()</h2>
-
-<p>Permits you to set the table heading. You can submit an array or discrete params:</p>
-
-<code>$this->table->set_heading('Name', 'Color', 'Size');</code>
-<code>$this->table->set_heading(array('Name', 'Color', 'Size'));</code>
-
-<h2>$this->table->add_row()</h2>
-
-<p>Permits you to add a row to your table. You can submit an array or discrete params:</p>
-
-<code>$this->table->add_row('Blue', 'Red', 'Green');</code>
-<code>$this->table->add_row(array('Blue', 'Red', 'Green'));</code>
-
-<p>If you would like to set an individual cell's tag attributes, you can use an associative array for that cell. The associative key <dfn>'data'</dfn> defines the cell's data. Any other key =&gt; val pairs are added as <dfn>key='val'</dfn> attributes to the tag:</p>
-
-<code>$cell = array('data' => 'Blue', 'class' => 'highlight', 'colspan' => 2);<br />
-$this->table->add_row($cell, 'Red', 'Green');<br />
-<br />
-// generates<br />
-// &lt;td class='highlight' colspan='2'&gt;Blue&lt;/td&gt;&lt;td&gt;Red&lt;/td&gt;&lt;td&gt;Green&lt;/td&gt;
-</code>
-
-<h2>$this->table->make_columns()</h2>
-
-<p>This function 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:</p>
-
-<code>
-$list = array('one', 'two', 'three', 'four', 'five', 'six', 'seven', 'eight', 'nine', 'ten', 'eleven', 'twelve');<br />
-<br />
-$new_list = $this->table->make_columns($list, 3);<br />
-<br />
-$this->table->generate($new_list);<br />
-<br />
-// Generates a table with this prototype<br />
-<br />
-&lt;table border="0" cellpadding="4" cellspacing="0"&gt;<br />
-&lt;tr&gt;<br />
-&lt;td&gt;one&lt;/td&gt;&lt;td&gt;two&lt;/td&gt;&lt;td&gt;three&lt;/td&gt;<br />
-&lt;/tr&gt;&lt;tr&gt;<br />
-&lt;td&gt;four&lt;/td&gt;&lt;td&gt;five&lt;/td&gt;&lt;td&gt;six&lt;/td&gt;<br />
-&lt;/tr&gt;&lt;tr&gt;<br />
-&lt;td&gt;seven&lt;/td&gt;&lt;td&gt;eight&lt;/td&gt;&lt;td&gt;nine&lt;/td&gt;<br />
-&lt;/tr&gt;&lt;tr&gt;<br />
-&lt;td&gt;ten&lt;/td&gt;&lt;td&gt;eleven&lt;/td&gt;&lt;td&gt;twelve&lt;/td&gt;&lt;/tr&gt;<br />
-&lt;/table&gt;</code>
-
-
-
-<h2>$this->table->set_template()</h2>
-
-<p>Permits you to set your template. You can submit a full or partial template.</p>
-
-<code>
-$tmpl = array ( 'table_open'&nbsp;&nbsp;=> '&lt;table border="1" cellpadding="2" cellspacing="1" class="mytable">' );<br />
-
-<br />
-$this->table->set_template($tmpl);
-</code>
-
-
-<h2>$this->table->set_empty()</h2>
-
-<p>Let's you set a default value for use in any table cells that are empty. You might, for example, set a non-breaking space:</p>
-
-<code>
-$this->table->set_empty("&amp;nbsp;");
-</code>
-
-<h2>$this->table->clear()</h2>
-
-<p>Lets you clear the table heading and row data. If you need to show multiple tables with different data you should
-to call this function after each table has been generated to empty the previous table information. Example:</p>
-
-<code>
-$this->load->library('table');<br />
-<br />
-$this->table->set_heading('Name', 'Color', 'Size');<br />
-$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 $this->table->generate();<br />
-<br />
-<kbd>$this->table->clear();</kbd><br />
-<br />
-$this->table->set_heading('Name', 'Day', 'Delivery');<br />
-$this->table->add_row('Fred', 'Wednesday', 'Express');<br />
-$this->table->add_row('Mary', 'Monday', 'Air');<br />
-$this->table->add_row('John', 'Saturday', 'Overnight');<br />
-<br />
-echo $this->table->generate();
-</code>
-
-<h2>$this->table->function</h2>
-
-<p>Allows you to specify a native PHP function or a valid function array object to be applied to all cell data.</p>
-
-<code>$this->load->library('table');<br />
-<br />
-$this->table->set_heading('Name', 'Color', 'Size');<br />
-$this->table->add_row('Fred', '&lt;strong&gt;Blue&lt;/strong&gt;', 'Small');<br />
-<br />
-$this->table->function = 'htmlspecialchars';<br />
-echo $this->table->generate();<br />
-</code>
-
-<p>In the above example, all cell data would be ran through PHP's <dfn>htmlspecialchars()</dfn> function, resulting in:</p>
-
-<code>&lt;td&gt;Fred&lt;/td&gt;&lt;td&gt;&amp;lt;strong&amp;gt;Blue&amp;lt;/strong&amp;gt;&lt;/td&gt;&lt;td&gt;Small&lt;/td&gt;</code>
