Javascript 拖放到google Visualization datatable数组中

我是网络开发和编码的初学者，所以很抱歉，如果我问了一个琐碎的问题

我想创建一个带有时间线的作业计划工具，因此我可以在网上找到这个基于google Visualization api的示例

almende.github.io/chap links library/js/timeline/examples/example15_mobile.html

现在一切正常，但我创建了一个包含两列的表：

<table width="1300" height="100%" border="1" cellpadding="1" cellspacing="1">
  <tr>
    <th width="250" align="left" valign="top" scope="row"><div id="jobs"><p>JOBS</p>
        <div class="timeline-event timeline-event-range ui-widget ui-state-default available" style="position: absolute; width: 171.66209509852223px;"><div class="timeline-event-content">available</div></div><br></br>
        <div class="timeline-event timeline-event-range ui-widget ui-state-default unavailable" style="position: absolute; width: 222.4193548387097px;"><div class="timeline-event-content">unavailable</div></div>
    </div></th>
    <td width="850" align="left" valign="top"><div id="mytimeline"></div></td>
  </tr>


</table>

这是我在时间轴上看到的日期范围。。。并具有以下功能：

$（'#mytimeline'）.width（）我得到时间线的像素，所以现在我可以计算1像素=时间

现在，当我将div对象从第1列拖动到第2列（#mytimeline）时，如何将div对象拖动到timeline中

请帮助我并为我的英语感到抱歉，它不好，但我正在努力学习

$(function() {
    $( "div.available" ).draggable();
  });
and yes its draggable but HOW I can add it to the dataTable

// Called when the Visualization API is loaded.
    function drawVisualization() {
        // Create and populate a data table.
        data = new google.visualization.DataTable();
        data.addColumn('datetime', 'start');
        data.addColumn('datetime', 'end');
        data.addColumn('string', 'content');
        data.addColumn('string', 'group');
        data.addColumn('string', 'className');

        // create some random data
        var names = ["Algie", "Barney", "Chris", "Pera", "Mile"];
        ime = names;
        for (var n = 0, len = names.length; n < len; n++) {
            var name = names[n];
            var now = new Date();
            var end = new Date(now.getTime() - 12 * 60 * 60 * 1000);
            for (var i = 0; i < 5; i++) {
                var start = new Date(end.getTime() + Math.round(Math.random() * 5) * 60 * 60*1000);
                ekstra = new Date();
                var end = new Date(start.getTime() + Math.round(4 + Math.random() * 5) * 60 * 60 * 1000);

                var r = Math.round(Math.random() * 2);
                var availability = (r === 0 ? "available" : (r === 1 ? "unavailable" : "maybe"));
                var group = availability.toLowerCase();
                var content = availability;
                data.addRow([start, end, content, name, group]);
