444<p>Like most other classes in CodeIgniter, the Table class is initialized
445in your controller using the <code class="docutils literal"><span class="pre">$this-&gt;load-&gt;library()</span></code> method:</p>

447</pre></div>
448</div>
449<p>Once loaded, the Table library object will be available using:</p>
450<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">table</span>

456<p>Here is an example showing how you can create a table from a

472<p>Here is an example of a table created from a database query result. The
473table class will automatically generate the headings based on the table
474names (or you can set your own headings using the <code class="docutils literal"><span class="pre">set_heading()</span></code>
475method described in the class reference below).</p>
476<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">library</span><span class="p">(</span><span class="s1">&#39;table&#39;</span><span class="p">);</span>

722<p>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.
723This allows a single array with many elements to be displayed in a table that has a fixed column count. Consider this example:</p>
724<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$list</span> <span class="o">=</span> <span class="k">array</span><span class="p">(</span><span class="s1">&#39;one&#39;</span><span class="p">,</span> <span class="s1">&#39;two&#39;</span><span class="p">,</span> <span class="s1">&#39;three&#39;</span><span class="p">,</span> <span class="s1">&#39;four&#39;</span><span class="p">,</span> <span class="s1">&#39;five&#39;</span><span class="p">,</span> <span class="s1">&#39;six&#39;</span><span class="p">,</span> <span class="s1">&#39;seven&#39;</span><span class="p">,</span> <span class="s1">&#39;eight&#39;</span><span class="p">,</span> <span class="s1">&#39;nine&#39;</span><span class="p">,</span> <span class="s1">&#39;ten&#39;</span><span class="p">,</span> <span class="s1">&#39;eleven&#39;</span><span class="p">,</span> <span class="s1">&#39;twelve&#39;</span><span class="p">);</span>
