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>
