Twitter bootstrap fixed table header using jQuery
Raw
README.txt
Here is a simple jQuery plugin to make a table header fixed on top of a div when this is scrolled.
Using the code from twitter bootstrap documentation page, this code is customized for table header.
Create the table with following layout -
<div class="row fixed-table">
<div class="table-content">
<table class="table table-striped table-fixed-header" id="mytable">
<thead class="header">
<tr>
<th>Email Address</th>
<th>First Name</th>
<th>Last Name</th>
<th>Administrator</th>
</tr>
</thead>
<tbody>
<tr>
<td>[email protected]</td>
<td>firstname</td>
<td>LastName</td>
<td>Data Column 4</td>
</tr>
...
</tbody>
</table>
</div>
</div>
Add the css from the file "table-fixed-header.css"
To apply it to above table, call -
$('.table-fixed-header').fixedHeader();
You need to assign a height value to ".table-content" into the css file.

When data overflows in X and Y both direction, then Vertical Scrollbar's top part is hidden by fixed header . Finding it difficult to fix.
