      function functionAdd() {
 
/* **> here I add cells and rows to the table** */

            var table = document.getElementById("id");
            var row = table.insertRow(1);
            var cell = row.insertCell(0);
            var cell1 = row.insertCell(1);
            var cell2 = row.insertCell(2);
            var cell3 = row.insertCell(3);
             cell.innerHTML = "New function";
             cell1.innerHTML = "<div class='row'>"+
              " <button type='button' id='on'>ON</button>"+

/* **>      there is the condition for buttons** */

    document.getElementById('on').disabled = false;
    document.getElementById('off').disabled = false;
        //on click changes on/off to green
        document.getElementById('on').onclick = function(){
          this.disabled = true;
          document.getElementById('off').disabled = false;
          if (this.disabled == false) {
            document.getElementById('off').disabled = true;

我找到了解决方案..花了一段时间原来如此

</head>
<body>

<script type="text/javascript">
var contor=0;
    function functionAdd() {
        var index=contor;
        var table = document.getElementById("id");
        var row = table.insertRow(1);
        var cell = row.insertCell(0);
        var cell1 = row.insertCell(1);
        var cell2 = row.insertCell(2);
        var cell3 = row.insertCell(3);
         cell.innerHTML = "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;New function";
         cell1.innerHTML = "<div class='row'>"+
          " <button type='button' id='on"+index+"'>ON</button>"+
          " <button type='button' id='off"+index+"'>OFF</button>"+
          "</div>";
         cell1.style.width = '100px';
         cell2.innerHTML = "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<img src='greenPoint.png' style = 'width: 10px; height:10px;'>"
         cell3.innerHTML = "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<img src='deleteIcon.png' style = 'width: 20px; height:20px;'>"

    document.getElementById("on"+index).disabled = true;
    document.getElementById("off"+index).disabled = false;
    //La click se schimba indicatorul on/off la verde
    document.getElementById("on"+index).onclick =function(){ generatorOn(index, cell2);};
    //La click se schimba indicatorul on/off la rosu
    document.getElementById("off"+index).onclick =function(){ generatorOff(index, cell2);};
    contor++;
    //console.log(contor);
}
function generatorOn(rowNumber, cell2){
  cell2.innerHTML = "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<img src='greenPoint.png' style = 'width: 10px; height:10px;'>";
  document.getElementById("on"+rowNumber).disabled = true;
  document.getElementById("off"+rowNumber).disabled = false;
}
function generatorOff(rowNumber, cell2){
  cell2.innerHTML = "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<img src='redPoint.png' style = 'width: 10px; height:10px;'>";

function generatorOff(rowNumber, cell3){
  cell3.innerHTML = "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<img src='deleteIcon.png' style = 'width: 20px; height:20px;'>";

}

</script>

  <div id="vizibilitate">
    <input type="button" value="Add function" onclick="functionAdd()" style="border-radius: 5px; margin-left: 500px; width:350px; height: 30px;">

          <tr>
              <th>denumirea</th>
              <th>statut</th>
              <th>on/off</th>

          <tr>
            </tr>
      </table>
