jQuery中的datatable 插件新增一行

<tr>
<td><input type="button" onclick="addRow(this)"</td>
</tr>

function addRow(currentButton)
{

var row1 = $(currentButton).parent().parent();
var row2 = row1.clone();
$(row2.children()[0]).html(null);//把新增的OBID赋值为空
//$(row2.children()[0]).html(Date.now);//把时间赋值给OBID作为订单行的唯一标示符
//row2.insertAfter(row1);
//table.row.add(row2);
var rowNode = table
.row.add(row2)
.draw()
.node();
row1.after(rowNode);
