A browse function in my categories controller which displays all rows in the table:

Code:
// -------------------------------------------------------------------------

    // Function: browse()

    // Description: Extracts a list of all categories and

    //              displays it.

    function browse()

    {

        $this->load->model('categories_model');    // Instantiate the model

        // fetch query object from categories with fields id, name

        $template['categories_list'] = $this->categories_model->fetch('categories','id, name');

        // create urls for use in content view

        $template['base_url']   = 'concentric/categories/browse/';

        $template['modify_url'] = 'concentric/categories/modify/';

        $template['delete_url'] = 'concentric/categories/delete/';

        $template['add_url']    = 'concentric/categories/add/';

        $template['cancel_url'] = 'concentric/home';

        // set values for use in content view

        $template['form_attributes'] = array('name' => 'frmcc_categories', 'id' => 'frmcc_categories');

        $template['header'] = $this->form_name;

        // build content html using grid view and template data

        $data['content'] = $this->load->view('/concentric/categories/categories_grid', $template, TRUE);

        // set values for use in header view

        $data['header']  = $this->form_name;

        // pass all data to container view and display to user

        $this->load->view('/concentric/container',$data);

    }

In the contructor of this controller, other libraries get called which set values that are then output in the header view.

Code:
$this->page->set_metatag('robots','nofollow, noindex');

        $this->page->set_metatag('pragma','nocache',TRUE);

(BackendPro users may recognize these functions.)

The categories_grid view contains this code:

Code:
<h2>&lt;?=$header?&gt;</h2>

<table width="100%" border="0" cellspacing="1" cellpadding="0">

<tr>

    <th align="right">

    <div class="buttons">

        <a href="&lt;?=site_url($add_url)?&gt;" class="blue">

        &lt;?= $this->page->icon('add');?&gt;

        Add

        </a>

    </div>

    </th>

</tr>

</table>

<br />

<table class="tbl" border="0" cellpadding="2" cellspacing="1" width="100%">

<thead>

<tr>

    <th align="right" width="70"> &nbsp; sort by:&nbsp; </th>

    <th VALIGN='MIDDLE' ALIGN='CENTER'  class='tbl_headercell'>

        Id

    </th>

    <th VALIGN='MIDDLE' ALIGN='CENTER'  class='tbl_headercell'>

        Name

    </th>

</tr>

</thead>

<tbody  class="scrollingContent">

    &lt;?

        $i = 0;

        foreach ($categories_list->result_array() as $categories) {

            $i++;

            if (($i%2)==0) { $bgColor = "#FFFFFF"; } else { $bgColor = "#C0C0C0"; }

    ?&gt;

    <tr bgcolor="&lt;?= $bgColor; ?&gt;">

        <td align="center" nowrap="nowrap">

            <a href = "&lt;?= site_url($modify_url).">Edit</a>

            &nbsp;&nbsp;&nbsp;

            <a href = "&lt;?= site_url($delete_url).">Delete</a>

        </td>

        <td align="left" nowrap="nowrap">&lt;?= $categories['id']; ?&gt;</td>

        <td align="left" nowrap="nowrap">&lt;?= $categories['name']; ?&gt;</td>

    </tr>

        &lt;? } ?&gt;

</tbody>

</table>

<br />

<div class="buttons">

    <a href="&lt;?=site_url($cancel_url)?&gt;" class="negative">

    &lt;?= $this->page->icon('cross');?&gt;

    Cancel

    </a>

</div>

and then the content view has this code:

Code:
<div id="navigation">

    &lt;?=$this->load->view('concentric/menu');?&gt;

</div>

<div id="content">            

    <a name="top"></a>

    &lt;?=$this->status->display();?&gt;

    &lt;?=(isset($content)) ? $content : NULL; ?&gt;

</div>

This may not be the best code or the most efficient, but after only 2-3 weeks of using CodeIgniter (and with very little prior experience in php), I think it is pretty good.
