The utility table is the table of utilities found in the node edit pane when the node specified by the node name and node label (the currently selected node) is a utility node.
Only if you have chosen to specify the table manually (alternative to using expressions), you can see the utility table. Otherwise, you see the table of expressions specifying the utility table.
The utility table specifies a utility function. For each configuration of the states of the parents, the utility table has an entry specifying a utility value of this configuration. Figure 1 shows the utility table of a utility node with two parents (Active and Color).

Each numeric value in the utility table is the utility of the parent nodes being in the states found in the top of the actual column.
You can change a specific numeric value by selecting it with the mouse cursor and typing in a new value from the keyboard.
