I'm trying to create some tables without borders. I select the table, go to the 'Table' section of 'Properties' and click on all the borders. This ostensibly seems to work as the '1pt Solid Line' entry in the 'Borders' section disappears, but the table isn't updated on the page. As soon as I click out of the properties tab all the borders reappear. They're also still there in the Preview view.
I'm using v1.5.2. Am I doing something wrong, or is this functionality currently bugged?
