How to filter webform results
I am not sure if you still need this information, but for the benefit of others...


You might want to look into the webform_mysql_views module.
If you are using drupal 7+, you can create a simple view of the "Webform Submissions" type. Then, under Fields you should be able to find Webform Submissions: Data Value field. Select that and then add the field you want to show up in your table. Do this for the rest of the fields you want. Finally, add the filters and/or sorts the very same way. NOTE: You might have to add a relationship (the very right drop-down) or two to show you relevant results.


Hope this helps!
