I am trying to create a template for users to create wiki pages from that has a column of fixed headings on the left and editable regions on the right. I have created a copy of the EnterpriseWiki.aspx file and am editing this. I've mangaged to get this to come up as a page layout you can select and I have managed to move the modified by area to the bottom of the page. I have also managed to create the editable regions using Sharepoint Designer, but can't work out how to add a column to the left of the editable regions.
I don't have any html skills so am trying to do this all just in Sharepoint designer.
