Just a little question, in a number cell, it is possible to have a "-" appear in front of the value if the value is negative. (Inspector->data formatting of the field).
But the other way round, how can i make a "+" sign appear if the value is positive?
I need the + sign because the fields are going to contain tolerances so there will be examples like this:
25.12 - 0.10 +0.05
25.12 -0.05 - 0.12
25.12 + 0.05 + 0.18
