hide some table row according to multiple checkbox selection with jquery

Question

Hi I have 2 tables like this with some checkbox for filter the table:

<label><input type="checkbox" name="chk_filter_Grocery_1" id="chk_filter_Grocery_1_1" value="1;">Alamond</label>
<label><input type="checkbox" name="chk_filter_Grocery_1" id="chk_filter_Grocery_1_2" value="14;">Apple</label>
<label><input type="checkbox" name="chk_filter_Grocery_1" id="chk_filter_Grocery_1_3" value="5;6;">Lemon & Orange</label>
<label><input type="checkbox" name="chk_filter_Grocery_1" id="chk_filter_Grocery_1_4" value="17;">Coconut</label>

<table width="620px" id="Grocery-NA768">
    <tbody>
        <tr class="14">
            <td width="185" height="35" align="left">Apple</td>
            <td width="65" height="35" align="center" valign="middle">3 Kg</td>

            <td height="35" align="center" valign="middle">27/04/2011&nbsp;</td>
        </tr>
    </tbody>
</table>

<label><input type="checkbox" name="chk_filter_Wine_1" id="chk_filter_Wine_1_1" value="51;">Brunello di Montalcino</label>

        </tr>
        <tr class="51">
            <td height="35" align="left">Brunello di Montalcino</td>
            <td height="35" align="center" valign="middle">3 b.</td>
            <td height="35" align="center" valign="middle">27/04/2011&nbsp;</td>
        </tr>
        <tr class="64">
            <td height="35" align="left">Pinot noir</td>
            <td height="35" align="center" valign="middle">3 b.</td>
            <td height="35" align="center" valign="middle">27/04/2011&nbsp;</td>
        </tr>
    </tbody>
</table>

The two table have a different id (Grocery-NA768) and (Wine-NA768) and each checkbox has one or more (max 2) value (1;12;) and every of the table has the corresponding number as class.

I would like to filter the table clicking on the checkbox. Ie when I click the apple checkbox (value 14) I want to see only the apple in the table (class 14), then if I click on the citrus (value 1;12;) checkbox I will see apple (class 14), lemon (class 5)and orange. If I deselect all the checkbox I will see the whole list. Same thing for the wine table. I site new of jquery and I've found how to show or hide table row clicking on a checkbox but nothing similar to my needs.

Thanks in advance Michele

Working example: http://jsfiddle.net/petersendidit/6dNKA/3/

See comments in the code:

// Define some config objects and loop over them to get things set up
$.each([{
    table: $("#Grocery-NA768"),
    inputs: $("input[name='chk_filter_Grocery_1']")
},{
    table: $("#Wine-NA768"),
    inputs: $("input[name='chk_filter_Wine_1']")
}],function(i, obj){
    var list = [];
    obj.inputs.click(function() {
        var that = $(this),
            value = that.val().match(/\d+/g),
            rows = obj.table.find("tr");

        // If its checked then add it to the list
        if ( that.prop("checked") ) {
            list = $.merge(list, value);
        } else {
            // if its not then remove the items from the list
            list = $.map( list, function( x ) {
                return ( $.inArray( x, value ) > -1 ) ? null : x;
            });
        }
        // If the list has items
        if ( list.length ) {
            rows.hide() // hide all rows
                .filter("."+list.join(",.")) // find the ones we care about
                .show(); // and show them
        } else {
            // If no items in the list
            rows.show(); // show every row
        }
    });
});
