Sets the cell shading as a vector/matrix of pattern indices (0–15):

nltShade 0 0 2 0

The shadings are reshaped to match the cells. Values are from 0 (unshaded) to 7 (90% grey). Various other patterns are available using numbers from 9 to 15 (which is solid black). See Patterns in the RainPro workspace for some examples. In general, values above 3 should only be used if you also set the text colour to white.

Cell shading is supported by both Spread and List.
