<p class="tip">
<em>NOTE!</em>
</p>
<ul>
<li>This functionality is new as of version 2.0.10 (not part of the original plugin).</li>
<li>When a column is sorted numerically ( <code>sorter:"digit"</code> ) any text in that column will, by default, be given a <em>zero</em> value. Sort the last column (#9) to see the problem with this method.</li>
<li>Overall <code>stringTo</code> option added in version 2.1.16.</li>
<li>String options changed in version 2.1.16; setting the value to:
<ul>
<li><code>"max"</code> will treat any text in that column as a value greater than the <em>max</em> (more positive) value. Renamed from "max+".</li>
<li><code>"min"</code> will treat any text in that column as a value greater than the <em>min</em> (more negative) value. Renamed from "max-".</li>
<li><code>"top"</code> will always sort the text to the top of the column.</li>
<li><code>"bottom"</code> will always sort the text to the bottom of the column.</li>
<li><code>"none"</code> or <code>"zero"</code> will treat the text as if it has a value of zero.</li>
</ul>
</li>
<li>Individual columns can be modified by adding the following (they all do the same thing), set in order of priority:
<ul>
<li>jQuery data <code>data-string="top"</code>.</li>
<li>metadata <code>class="{ string: 'top'}"</code>. This requires the metadata plugin.</li>
<li>headers option <code>headers : { 0 : { string : 'top' } }</code>.</li>
<li>header class name <code>class="string-top"</code>.</li>
<li>Overall <code>stringTo</code> option.</li>
</ul>
</li>
<li>Sort columns three through eight to see how the sort has changed. Note that the text is sorted separately from the numeric values.</li>
<li>The <code>emptyTo</code> option defaults to bottom, so all empty cells will sort at the bottom of the table, except for the second column.</li>
</ul>
