我要做的是从表中恢复数据并动态添加到表中供用户编辑。事情是，当用户单击Προσθηκη以添加带有addRow函数的新空字段时，我无法找到方法。

JavaScript的：
function insertRow(position) {
var table = document.getElementById("theTable");
var tr = table.insertRow(position);
var td = tr.insertCell(0);
tr.insertCell(1);
tr.insertCell(2);
var textNode = document.createTextNode("\u00A0");
td.appendChild(textNode);
}
jQuery的：
function insertRow() {
$("#theTable").append("<tr><td> </td><td></td><td></td></tr>");
}
