Time Worked: 1 day
Time Spent: 1 day
working on this. I had problems making the patch work and I had to apply
changes manually. I'de like to review it more carefully before committing it,
and I would not change or deprecate anything from 1.1 in this release.
> TableDecorator created with 1.0 doesn't work properly with 1.1. Properties
