The default property of a Layer object is Name.
To access cells whose values define layer attributes, such as whether the layer is visible or printable, use the CellsC property.
A layer's Index and Row properties typically have different values. The Index property indicates the layer's ordinal position in its Layers collection. The layer's Row property indicates the index of the row in the Layers section where the layer's attributes are defined.
