Pisa is not able to split table cells that are larger than the available space. To work around it you may define what should happen in this case. The -pdf-keep-in-frame-mode can be one of: "error", "overflow", "shrink", "truncate", where "shrink" is the default value.
table {
-pdf-keep-in-frame-mode: shrink;
}Since Reportlab Toolkit does not yet support the use of images within paragraphs, images are always rendered in a seperate paragraph. Therefore floating is not available yet.
