I'm trying to make a sidebar in a Libreoffice writer document, exactly like in the following template.
The sidebar should have a different background color and a separate text section, but vertically aligned with the content on the right (the sidebar will be used for headings, while the right section will be used for actual content).
A two column table seems appropriate for this, the left column holds the headings and the right one holds the content, but the sidebar's background color should fill the whole left part of the document (a vertical strip) without any margins, so I should set the margins to zero. The problem is, I need the margins for the text, and I somehow need the table's background color to ignore them.
I understand this may not be a good fit for Writer (and I can make the same document without any issues in HTML/CSS or a graphics editor like Photoshop), but I really need it in writer (the document is for someone else who won't accept an HTML or Photoshop version).
