jQuery: table with grouping and sum in group footer/header?
<p>I'm looking for a jQuery-solution which enables sorting and grouping by columns; then, in the footer section, it should be possible to show the sum of all values above.</p>

<p>Example: I've got three columns: Country, Date and Sales:</p>

<pre><code>US     20120714       50
DE     20120714       40
BR     20120714       30
US     20120715       60
DE     20120715       60
BR     20120715       20
</code></pre>

<p>If I sort by country:</p>

<pre><code>BR     20120714       30
BR     20120715       20
                      50
DE     20120714       40
DE     20120715       60
                     100
US     20120714       50
US     20120715       60
                     110
</code></pre>

<p>If I sort by date:</p>

<pre><code>BR     20120714       30
DE     20120714       40
US     20120714       50
                     120
BR     20120715       20
DE     20120715       60
US     20120715       60
                     140
</code></pre>

<p>and so on...</p>

<p>Is there a plugin available for this?</p>
