theming the results submission table due to overflow issues.

problem im having is my table for displaying the submitted info. i'd like to set the css for the overflow to visible but not for the entire site's tables obviously (just let me know if im on the right track here or if theres another way) but since it displays the table without any divs specific to this module, i'm assuming i have to copy the function for the 'node/24/results/table page' which appears to be in 'webform_report.inc' which is in the module's folder, and looks like:

/**
 * This function creates a table for all submissions.
 * @param $nid
 *   The node ID of the node to show results for.
 */
function _webform_results_table($nid) {
  include_once(drupal_get_path('module', 'webform') ."/webform.inc");
  // Load Components.
  _webform_load_components();

and somehow theme it with the correct div in proper template.php syntax...seems a headache and i've never done that yet. wishing there was an easier way. but is this the right function i'm looking at (most specifically for the Table view)? And i know you're not here to give a lesson on theming but anything is welcome at this point.

second quick question: does the publishing options (submitted, or the others) make any kind of DB difference with webforms module? i have submitted checked, but do i need it checked? just wondering if there's any database tables filling up with useless information.
