jQuery Validator fields that use php style names with brackets and can be dynamically added

I have an entry grid that allows you add rows to it dynamically.  The names of the fields in the row are all the same followed by a bracket [] for php processing.  For example, here is a single row in the form table:

  1. <tr>
     <td class="hidden"><input type="hidden" id="muId[]" name="muId[]"></td>
         <td>
            <select class="markup-cost-type" name="muCostType[]">
                <option selected="selected">Labor</option>
                <option>Material</option>
                <option>Subcontract</option>
                <option>Equipment</option>
                <option>Other</option>
                <option>Overhead</option>
            </select>                        
        </td>
        <td><input type="text" size="2" maxlength="3" value="1" name="muOrder[]" /></td>
        <td>
            <select class="markup-markup-item" name="muItem[]">
                <option>Profit</option>
                <option selected="selected">Overhead</option>
                <option>Sales Tax</option>
            </select>                        
         </td>
         <td><input name="muAmount[]" type="text" size="9" value="20.0000" /></td>
        <td><input class="markup-effective-date" name="muEffectiveDate[]" type="text" size="9" value="1/1/2010" /></td>
        <td><input class="markup-expire-date" name="muExpireDate[]" type="text" size="9" value="12/31/2010" /></td>
        <td><input type="checkbox" name="muCumulative[]" value="3" /></td>
        <td><input type="checkbox" name="muEnable[]" value="3" checked="" /></td>
        <td><img class="markup-remove-row" height="16" width="16" src="img/delete.png" class="control"></td>
    </tr>


There will be an unlimited number of rows depending on how many the user choses to add.  Each field should be validated independently, so all the muEffectiveDate[] field cannot be treated as a group using a class rule.  I know that using the basic rule syntax requires unique names for each field so I am hoping there is another way to get the rules associated with each input in every row.  Even if there is not and I have to add some sort of index number and a way to manage those numbers dynamicly (as rows can also be removed at will), would i need 100 rules if i had a 100 line table with 100 muEffectDate[index] fields?  I feel there must be a better way to do this as I image this kind of validation is common for something like an order entry system or anything else that requires grid style entry.
