table is expanding past the right edge of jquery tab

[nam797]

I'm calling ajax request and it's returning the fixedHeaderTable with data and everything. on certain pages it extends past the right side of the jquery tab. I have tried to adjusting the width and that gives me more horizontal scrolling. this is the code that generates what is being return.
this is the ajax call:
$.ajax({
url: 'ajax_dash.php?action=emp_stats_data&beg='+begining+'&end='+end,
type: "GET",
success: function(feedback){
$('#cont').html('');
$('#cont').html(feedback);
}
});
this is what is happening at the call:

<script> $(function() { $( "#begining" ).datepicker({ dateFormat: 'yy-mm-dd' }); $( "#end" ).datepicker({ dateFormat: 'yy-mm-dd' }); $('#instats').fixedHeaderTable({ width: '100%', height: '250', footer: false, cloneHeadToFoot: false, altClass: 'odd', themeClass: 'fancyTable',autoShow: false }); $('#instats').fixedHeaderTable('show', 700); //$( "#add_remid" ).button(); }); </script>

               <table id="instats" cellpadding="0" cellspacing="0">
                    <thead>
                        <tr>
                            <th>Caller</th>
                            <th>Leads Issued</th>
                            <th>Wages</th>
                            <th>Hours Worked</th>   
                            <th>Lead Cost</th>  

                        </tr>
                    </thead>
                    <tbody>
                        <?php
                            $q = "SELECT EmployeeID FROM empmain WHERE Department = 80 and Status = 'Active'";
                            $dResult = mysql_query($q) or die(mysql_error());

                            $num = mysql_num_rows($dResult);;
                            if ($num < 1)
                            {
                                echo "<tr><td>No Records Found</td><td></td><td></td><td></td><td></td></tr>";
                            }
                            else
                            {
                               while ($row = mysql_fetch_array($dResult))
                               {
                                   $num_leads = $database->get_leads_by_date_inside_sales($row['EmployeeID'],$date_start,$date_end);
                                   $rep = $database->GetEmpNameCell($row['EmployeeID']);
                                   echo '<tr>';
                                   echo "<td>$rep[EmpName]</td>";
                                   echo "<td>$num_leads</td>";
                                   echo "<td><input class=\"text ui-widget-content ui-corner-all\" type=\"text\" name=\"wages\" id=\"wages\" /></td>";
                                   echo "<td><input class=\"text ui-widget-content ui-corner-all\" type=\"text\" name=\"hours\" id=\"hours\" /></td>";
                                   echo "<td>$</td>";

                                   echo '</tr>';
                               }
                            }
