Hi,
There's a table creator icon on the toolbar that gives a popup-fill-in for creating an HTML table. The basic code for table looks like this:
<table cellpadding="0" cellspacing="0" border="0" style="background:#ff0000;"><tr><td>
<!--All other code here.-->
</td></tr></table>
That's creating a single table cell that acts as the container for the template elements and I included a red background color. I didn't put a width on the table in this example. The syntax for table is here:
