Benoy Antony commented on HDFS-6407:
------------------------------------

To add sorting to do a new table, the following needs to be done. (More details in http://mottie.github.io/tablesorter/docs/index.html)

1. In the page containing table, include the css and js file
{code}
<link rel="stylesheet" type="text/css" href="/static/tablesorter.default.css" />
<script type="text/javascript" src="/static/jquery.tablesorter.min.js"> </script>
{code}

2. Attach table sorter style on the table 

{code}
<table class="tablesorter-default">
{code}

3. Make sure that the table has THEAD and TBODY tags

4. Enable tablesorter to sort the table when the document is loaded.

{code}
$(".tablesorter-default").tablesorter({sortList: [[0,0]]});
{code}

> old ui supported clicking on column header to sort on that column. The new ui seems to have dropped this very useful feature.
> There are a few tables in the Namenode UI to display  datanodes information, directory listings and snapshots.
> When there are many items in the tables, it is useful to have ability to sort on the different columns.
