Is it possible to replace a table cell without deleting it with javascript or jQuery?

Is it possible to replace a table cell without deleting it with javascript or jQuery? For example, if I have a table with several rows, each row having 5 cells, could I change the first cell of the first row through assignment instead of removing the cell and then inserting a new one?

EDIT (simplified):

<table>
    <tr id="currentRowId1" name="currentRowId1">
        <td style="text-align:center">
        </td>
        <td style="text-align:center">
        </td>
        <td style="text-align:center">
            <input type="submit" onclick="changeOrder()" />
        </td>
        <td style="text-align:center">
        </td>
        <td>
        </td>
    </tr>
    <tr id="currentRowId2" name="currentRowId2">
        <td style="text-align:center">
        </td>
        <td style="text-align:center">
        </td>
        <td style="text-align:center">
            <input type="submit" onclick="changeOrder()" />
        </td>
        <td style="text-align:center">
        </td>
        <td>
        </td>
    </tr>
</table>

js

function changeOrder(){
var row = document.getElementById("currentRowId1");
var otherRow = document.getElementById("currentRowId2");
row.cells[0] = otherRow.cells[0];
}

There is acutally no need to work with innerHTML here. You could replace the two elements like this:

var
  a = document.getElementById('currentRowId1').cells[0],
  e = document.getElementById('currentRowId2').cells[0],
  e1 = e.nextSibling;

a.parentNode.replaceChild(e, a);
e1.parentNode.insertBefore(a, e1);

There are multiple ways to do this. You can set the inner html of the cell as fabianhjr pointed out. You can also build a new element in javascript/jquery and use jquery's replaceWith() method.

You can use other jquery methods that will replace the cells, clone() and before() or after() I know this isn't what you asked for just pointing out other options.

Example #1:

var me = $("#cellId");
var newHtml = $("<div>blah blah blah</div>");
me.replaceWith(newHtml);

Example #2:

var me = $("#cellId");
var clone = me.clone();
 // do some cool things with the clone change html whatever
me.replaceWith(clone);

You can't just assign the cell equal to something else like you tried in this line:

row.cells[0] = otherRow.cells[0];  // doesn't work

However, once you have a reference to the cell you can change what is inside it, e.g., to copy the contents from one cell to another:

row.cells[0].innerHTML = otherRow.cells[0].innerHTML;

You can also create, amend or remove the children of the cell via the reference to the cell.

If you are using jQuery there are a number of methods that achieve the same sort of thing, e.g., the following is equivalent to the above (but less efficient):

$(row.cells[0]).html( $(otherRow.cells[0].html() );

If you just want to change whats inside it you can use..

document.getElementById('nameofyourcell').innerHTML = 'content';
