Long description of example of cell background calculation
This diagram shows the six superimposed "layers" of the CSS
table model. This diagram illustrates the algorithm for
calculating a cell's final background.
The six layers are depicted as prioritized rectangles floating one
above the other in a three-dimensional space (i.e., layers are drawn
as rhombuses to give the impression of space). The rectangles
represent, from top to bottom: cells, rows, row groups, columns,
column groups, and the table itself.
The diagram shows how, looking down on the six rectangles, one may
compute the background color of each cell. On the top layer, each cell
that specifies a background is shown as a gray box with a black
border. A cell without a background color in the top layer is
depicted as a "window" onto the lower layers, which give its final
background color. The same visual metaphor is used at each layer, so a
row without a background acts as a window onto the row group layer,
etc.
