If you need to use Javascript innerHTML to update an element on the page you may run into issues if the element is a table. The correct way to updated the table element is through a <tbody> tag. You can then give it an ID that you can get with your javascript.
Example
<tbody id="updatedContent"> </tbody>
Then you can pass <tr> and <td> data into the <tbody> using innerHTML.
This is the way you will have to update a table using AJAX. without this technique you won't be able to add or update a table's data with AJAX.
