Use this procedure to create a nested grid, which is a grid within a grid. Each nested grid has its own division rules, cell assignments, frame, and mullions. By default, the frame is off for nested grids.
A new cell assignment is displayed in the list of cell assignments.
A new grid is added to the list of grids in the left pane of the dialog box. If you are editing the primary grid, the new grid is added at the secondary level. If you are editing a grid at the secondary level, the additional grid is placed at the tertiary level, and so on.
