使用JQuery sortable拖动时，表行偏移

Question

I have a table that uses border-spacing to separate rows.

When using JQuery sortable - and it works - the row jumps down when beeing moved, can this be fixed?

This code demonstrates:

 $(function() { $("#items").sortable(); $("#items").disableSelection(); }); 

 table { border-spacing: 0 20px; background-color: #cda; } td { width: 170px; border: 2px solid gray; } 

 <script type="text/javascript" src="http://code.jquery.com/jquery.min.js"></script> <script type="text/javascript" src="http://code.jquery.com/ui/1.9.2/jquery-ui.js"></script> <table> <tbody id="items"> <tr> <td class="list">1</td> </tr> <tr> <td class="list">2</td> </tr> <tr> <td class="list">3</td> </tr> </tbody> </table>

I found a solution. I added a class to the dragged element,

.up{
margin-top: -20px;
}

(It seems to correspond to the value of border-spacing )

The adding was by making the sortable call like this:

$(function () {
$("#items").sortable({
placeholder: "highlight",
start: function (event, ui) {
ui.item.toggleClass("up");
},
stop: function (event, ui) {
ui.item.toggleClass("up");
}
});
$("#items").disableSelection();
});
