With your cursor in the cell you want shaded, click fill change the color. Only the
cell with your cursor should change.
When you create a publication from a Publisher wizard or by using Publisher Design
Gallery
Objects, the individual objects that make up that publication are synchronized. This
synchronization means that any formatting changes that you apply to an individual
element within an object will automatically apply to the similar elements in that
object. For example, if you change the color of one shape in an Accessory Bar that
you insert from the Design Gallery, all of the related shapes in that Accessory Bar
will be updated with the same color automatically.
Turn off formatting synchronization
If Publisher applies a formatting change that you make to one element in an object to
all of the similar elements in an object, you can turn off the synchronization and
limit the change to the element that you initially selected.
On Edit menu, click Undo Synchronize.
Automatically synchronize formatting
The automatic formatting synchronization for an object will be turned off if you
click Undo Synchronize immediately after Publisher synchronizes a formatting change
that you have applied to an element in an object. You can reset the automatic
formatting synchronization for that object so that Publisher will once more
synchronize any changes that you make to elements of the object.
On the Tools menu, click Options, and then click the User Assistance tab.
Click Automatically synchronize formatting.
