XSL FO setting content to the bottom of the page fails

1
votes

I am trying to print table at the bottom of the page(A4 format), but instead of that, last table keeps printing after previous element, despite the fact of margin-bottom property. Additionaly, if I am trying to set footer (using fo:footnote with fo:inline) - this footer also appearing not in the bottom of the page, but under last element.

The margin-bottom property indicates that you want a space below the table. It has nothing to do with placing an object at the bottom of a page. If you want the table to appear at the bottom of the page, there are 2 options:

  1. insert it in the region-after area, not in the body area.
  2. Wrap it in a block-container which has an absolute position.

I put content I want at the bottom of the page into a footnote construct in an empty block with an empty inline citation. Let the formatter worry about where the bottom of the page is. I tell my students this is an appropriate approach for things like legal disclaimers at the bottom of the last page of a document.

The problem with an absolutely-positioned block-container is that if its dimensions overlap with the body, then it is possible for body content to overwrite it. If the body content is shrunk for that content, you need to accommodate the different areas in the page geometries.

I find it easiest just to throw it into a footnote.
