Investigate performance

Sorting a table with thousands of rows takes quite a bit of time if your machine is not very powerful.

There are some interesting notes here: http://madhatted.com/2008/1/16/the-joy-of-an-optimized-complete-javascript-table-sort And could look into using document fragments: https://developer.mozilla.org/en-US/docs/Web/API/Document/createDocumentFragment

On my terrible laptop, it took about 5 seconds just to call all the appendChilds after sorting.
