get the content of cells when selection by column (selectable)

get the content of cells when selection by column (selectable)

Hello,
my question is quite simple, but I can't manage to make it work properly

I have a table and I want all cells of the table to be "selectable" by using the selectable plugin of jquery UI

here below my table :
<table id=\"selectable\">
  <tr> <th class=\"ui-widget-content\">   A </th> <th class=\"ui-widget-content\">   B </th> <th class=\"ui-widget-content\">   C </th> </tr>
  <tr> <td class=\"ui-widget-content\">   1 </td> <td class=\"ui-widget-content\">   2 </td> <td class=\"ui-widget-content\">   3 </td> </tr>
  <tr> <td class=\"ui-widget-content\">  10 </td> <td class=\"ui-widget-content\">  20 </td> <td class=\"ui-widget-content\">  30 </td> </tr>
  <tr> <td class=\"ui-widget-content\"> 100 </td> <td class=\"ui-widget-content\"> 200 </td> <td class=\"ui-widget-content\"> 300 </td> </tr>
</table>

I want to check if I cant get the content of each cell that is "selected" by the mouse, when I select only through one column (not according to rows) :

then the javascript here below :
$(function() {
        $(\"#selectable\").selectable({
            stop: function(){
                var result = $(\"#select-result\").empty();
					contenu = $(\".ui-selected\").text();
					result.append(contenu);
            }
        });
    });

the result of this I can select with the mouse by column but my script get always the contect of ALL cells and not only the one selected !!

can you please help me ?
