I think what you have is almost correct, it just needs a small tweak: in
the loop where you reset the formatted values, try setting them to the
actual value instead of null. Some formatters modify the already-formatted
value rather than the base value. You'd want something like this (in your
pseudocode):
for {
weightsTable.setValue(i,2,weight);
weightsTable.setFormattedValue(i,2,weight);
}
