Sudoku 9x9 grid expands args
Sudoku 3x3 box table table with 9 boxes, main grid
Sudoku 3x3 box box with 3x3 cells
Sudoku 3x3 table table with 3x3 cells, int. grids only
3x3 box args:
1..9 cell digits,
gc - grid color, internal minor grid borders only
cellsize
c1..9 - cell background colors
Implementation Notes:
|= is a continuation trick, see{{Chess diagram}}
sN are the style tages for the 9 cells. Only internal borders are defined.
i.e. looks like a tic-tac-toe grid., sN contains:
cell border color style
cellsize
cell background color
Cells are intended to cover the box completely, table bgcolor should
have little impact.
If a cell has no value at all. it's grid borders will not display.
To avoid this, for blank cells, use  .
As a precaution, pass the grid color gc, to use as the table bgcolor.
If the cell border is not displayed, the 3x3 table body color shows, which will be the same.
