Hi,
Currently there is no direct way to remove the contents section from the published code. However, as a workaround, you can publish the code in HTML format and then edit the resultant HTML file to remove the contents section. To remove that section, you can search the "Contents" which is within <H2> tag and remove the heading and the following table from the HTML file. The removed part will look similar to the following:
<h2>Contents</h2>
<div>
<ul>
<li>
<a href="#1">Add an Odd Harmonic and Plot It</a>
</li>
<li>
<a href="#5">Note About Gibbs Phenomenon</a>
</li>
</ul>
</div>
I hope this helps.
