    <p>If you need to actually replace the td you are selecting from the DOM, then you need to first go to the parentNode, then <strike>replace the contents</strike> replace the innerHTML with a new html string representing what you want. The trick is converting the first-table-cell to a string so you can then use it in a string replace method.</p> <p>I added a fiddle example: <a href="http://jsfiddle.net/vzUF4/" rel="nofollow">http://jsfiddle.net/vzUF4/</a></p> <pre><code>&lt;table&gt;&lt;tr&gt;&lt;td id="first-table-cell"&gt;0&lt;/td&gt;&lt;td&gt;END&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt; &lt;script&gt; var firstTableCell = document.getElementById('first-table-cell'); var tableRow = firstTableCell.parentNode; // Create a separate node used to convert node into string. var renderingNode = document.createElement('tr'); renderingNode.appendChild(firstTableCell.cloneNode(true)); // Do a simple string replace on the html var stringVersionOfFirstTableCell = renderingNode.innerHTML; tableRow.innerHTML = tableRow.innerHTML.replace(stringVersionOfFirstTableCell, '&lt;td&gt;0&lt;/td&gt;&lt;td&gt;1&lt;/td&gt;'); &lt;/script&gt; </code></pre> <p>A lot of the complexity here is that you are mixing DOM methods with string methods. If DOM methods work for your application, it would be much bette to use those. <strike> You can also do this with pure DOM methods (document.createElement, removeChild, appendChild), but it takes more lines of code and your question explicitly said you wanted to use a string.</strike></p>

    2. COAh, yes, thanks EL 2002 I didn't understand that we wanted to keep END, so we are turning a 2 column table into a 3 column. I'll update example.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
