always be kept in first and/or last position, regardless of sorting. <code class="docutils literal notranslate"><span class="pre">len()</span></code> and indexing
will include them, which means that if theres a header, <code class="docutils literal notranslate"><span class="pre">table[0]</span></code> returns it and if
theres a footer, <code class="docutils literal notranslate"><span class="pre">table[-1]</span></code> returns it. To make things short, all list-like functions
work with header and footer “on”. But things get fuzzy for <code class="docutils literal notranslate"><span class="pre">append()</span></code> and <code class="docutils literal notranslate"><span class="pre">insert()</span></code>
because these will ensure that no “normal” row gets inserted before the header or after the
footer.</p>
<p>Adding and removing footer here and there might seem (and is) hackish, but its much simpler
than the alternative (when, of course, you need such a feature), which is to override magic
methods and adjust the results. When we do that, there the slice stuff that we have to
implement and it gets quite complex. Moreover, the most frequent operation on a table is
<code class="docutils literal notranslate"><span class="pre">__getitem__</span></code>, and making checks to know whether the key is a header or footer at each
call would make that operation, which is the most used, slower.</p>

<p>You can organize your attributes in whatever way you want, but theres a convention you can
follow if you want to minimize subclassing and use default behavior:</p>
<ol class="arabic simple">
<li>Attribute name = column name. If your attribute is <code class="docutils literal notranslate"><span class="pre">foobar</span></code>, whenever we refer to
<code class="docutils literal notranslate"><span class="pre">column_name</span></code>, you refer to that attribute with the column name <code class="docutils literal notranslate"><span class="pre">foobar</span></code>.</li>
<li>Public attributes are for <em>formatted</em> value, that is, user readable strings.</li>
<li>Underscore prefix is the unformatted (computable) value. For example, you could have
<code class="docutils literal notranslate"><span class="pre">_foobar</span></code> at <code class="docutils literal notranslate"><span class="pre">42</span></code> and <code class="docutils literal notranslate"><span class="pre">foobar</span></code> at <code class="docutils literal notranslate"><span class="pre">&quot;42</span> <span class="pre">seconds&quot;</span></code> (what you present to the user).</li>
<li>Unformatted values are used for sorting.</li>
<li>If your column name is a python keyword, add an underscore suffix (<code class="docutils literal notranslate"><span class="pre">from_</span></code>).</li>
</ol>
<p>Of course, this is only default behavior. This can be overriden.</p>
