Caveats

If cells are empty, their (subgrid) borders don't show. Instead you see the table background color. To insulate against this behaviour, the 3x3 table uses background color = grid color.

If all the cells of a box are empty, setting cellsize won't correct subgrid edge disconnects.

When called from Sudoku 9x9 grid, cell values are always set, nbsp is used for blank.
