Your bootstrap css is working fine--

class="table table-bordered table-condensed table-striped table-hover" - table-bordered table-condensed table-striped table-hover is not applied.. Am I missing some thing.

I got the answer. I have added <tbody></tbody>. After this all bootstrap class added related to table getting executed..

class="table table-bordered table-condensed table-striped table-hover"

var table = $('<table id="mytable" class="table table-bordered 
table-condensed table-striped table-hover"><tbody></tbody></table>');
