filtering table rows having rowspan

filtering table rows having rowspan

Hi,
 
I want to filter the rows of a table based on a specified filter for a particular column. However I am getting problems when my row has rowspan, since if a particular tr has rowspan then consecutive tr's have one less td(until the rowspan ends) which causes a wrong calculation of td positions, leading to incorrect filtering.
 
Kindly help. I have tried using uitablefilter .js ( http://gregweber.info/projects/demo/flavorzoom.html)
 
and table.js( http://www.javascripttoolbox.com/lib/table/ ) but no luck still.
 
Kindly help.
 
Thanks,
Harshit
