Can anyone offer an easy way to create a grid for use with this popular game? My friend wants instructions on creating the form, and I can easily provide her with the steps to make the basic table of 9 columns and 9 rows, with a size of .75" for each cell. I haven't figured out, though, how to create the heavier interior borders surrounding each of "sub-tables" - the nine groups each composed of 3 columns and 3 rows of cells.
I hope I've made this clear. Thanks for any ideas.
