The Hugin Graphical User Interface provides a number of powerful features for displaying node tables, including resizing, collapsing selected sets of columns, graphics display modes, etc.
The probabilities and utilities of discrete chance nodes and utility nodes, respectively, can be specified manually (i.e., directly through click-and-type operations) or they can be specified indirectly through specification of powerful expressions, which (if appropriate) can save a lot of work.
When working in Edit Mode with the Tables Pane open, the currently selected nodes will have their tables displayed in the Tables Pane.
See the Node Table Tutorial for more information on node tables.
