It is not possible to have variable row heights in a table. In other words,
all rows must be the same height. That doesn't prevent having cells that
have multiple lines of text, though. If you set the row height to be large
enough, e.g. with table.setRowHeight(40); you could then have a cell
renderer that rendered two lines (or more, if your row height is sufficient)
for a single cell.

That "should" be easy to do. Subclass qx.ui.table.pane.Pane and in your
subclass, add a new event, e.g. "changeFocus", and override the
setFocusedCell method to fire that event whenever it's called and the
focussed cell has actually changed.
You can then make your table use the subclass by using the "custom"
parameter to the Table constructor. Call your constructor like this:
var custom =
{
tablePane : function(obj)
{
return new my.custom.Pane()
}
};
var table = new qx.ui.table.Table(tableModel, custom);

Someone else more knowledgable about data binding than I will have to answer
this as it relates to data binding. There is very little difference,
however, between a TreeFolder and a TreeFile. The biggest difference is that
a TreeFolder can have children. If you just don't assign any children to it,
and you set the openSymbolMode property to either "never" or "auto", then
the open/close symbol will not appear. Maybe that solves your problem?
