Nothing magic. If we have:
if (a == 1) {
if (b == 1) {
} else if (b == 2) {
} else {
}
} else if (a == 2) {
if (b == 1) {
} else if (b == 2) {
} else {
}
} else {
}
we have a 3*3 table with actions in each cell.
They were particularly interested in it for proving theorems, but it
makes sense for chemistry. Of course the table can be
multidimensional and sparse.
