Sortable table

importance: 4

Make the table sortable: clicks on <th> elements should sort it by corresponding column.

Each <th> has the type in the attribute, like this:

<table id="grid">
      <th data-type="number">Age</th>
      <th data-type="string">Name</th>

In the example above the first column has numbers, and the second one – strings. The sorting function should handle sort according to the type.

Only "string" and "number" types should be supported.

The working example:

P.S. The table can be big, with any number of rows and columns.
