# Search term parser from https://gist.github.com/1477730
# Modified to allow periods (and other non-letter chars) in unquoted field values
# and field names.
#
# Helper class to help parse out more advanced saerch terms
# from a form query
#
# Note: all hash keys are downcased, so ID:10 == {'id' => 10}
#       you can also access all keys with methods e.g.: terms.id = terms['id'] = 10
#       this doesn't work with query as thats reserved for the left-over pieces

Here is a simple jQuery plugin to make a table header fixed on top when window is scrolled.
Using the code from twitter bootstrap documentation page, this code is customized for table header.

Create the table with following layout -
<table class="table-fixed-header">
  <thead class="header">
    <tr>
      <th>Column 1</th>
      <th>Column 2</th>
      <th>Column 3</th>

UPDATE: It's a gem!

This helper has finally been moved into a gem called nav_lynx!

http://rubygems.org/gems/nav_lynx

Thanks to @brianjlandau and @reagent for getting that set up and tested!

Behold, the nav_link:
