Add rows in HTML table with JavaScript

Question

I'd like to write <td> tags with JavaSctipt in my HTML code. I'm building a <table> in the main code and I'd like to continue it with a <script>, adding rows in the division.

<body>
  <table>
    <tr>
      <td>First</td>
    </tr>
    <div id="searchOutput"></div>
    <tr>
      <td>Last</td>
    </tr>
  </table>
  <script>
  document.getElementById("searchOutput").innerHTML = "<tr><td>Middle<td><tr>";
  </script>
</body>

The problem is that the <script> creates another table in a strange way.

Is there a way to add rows without writing all code (including <table> tags) in the <script>?

`table` children should not be `div`s. Try selecting the `table` and appending a `tr` to it, or selecting an existing `tr` and putting `td`s/text into it — CertainPerformance, Jun 16 '18 at 01:32
I already tried to insert the table data in various tag like `
` or `
` and the problem was already there. I also tried to put a `` in a `` but the result was always the same. — Marco Di Francesco, Jun 16 '18 at 10:49

For insert new row in the table, you can use Table insertRow() and insertCell() Methods. The insertRow() methods creates an empty <tr> element and adds it to a table. The insertCell() method inserts a cell into the current row.

See the code below:

function addRows() {
  var table = document.getElementById( 'myTable' ),
      row = table.insertRow(0),
      cell1 = row.insertCell(0),
      cell2 = row.insertCell(1);

  cell1.innerHTML = 'Cell 1';
  cell2.innerHTML = 'Cell 2';
}

table {
  border: 1px solid #999;
  border-collapse: collapse;
  width: 100%
}
td {
  border: 1px solid #999
}

<p>
  <button onclick="addRows()">Add a new row</button>
</p>
<table id="myTable"></table>

CertainPerformance is correct; divs should not be direct children of tables. You might find this question useful. You have the right idea, if only you could actually replace the HTML of the div as opposed to simply filling it in. So, you could set the ID of the Last tr to searchOutput. Then, something like

var newRow = document.createElement("tr");
var oldRow = document.getElementById("searchOutput");
newRow.innerHTML = "<tr><td>Middle</td></tr>";
document.getElementByTagName("table").insertBefore(row, oldRow);
