...so you can, for example, change the label that appears when computing the difference between a pair of rows:
A table with a Rule applied. This article uses the example from How to Compute the Difference Between a Pair of Rows in a Table. Note, Highlight Cells, Top/Bottom and Color Scale Rules cannot be modified in this way.
1. Select your table.
2. Go to Properties > RULES on the object inspector.
var new_row_label = row_label_1 + ' - ' + row_label_2; // Specify the label of the new row (containing the differences)
Instead of creating a label that concatenates the first selected row label with the second one, we can simply change this to Difference as follows:
var new_row_label = "Difference";
5. Press OK > OK.
Note, if this Rule was originally applied to multiple tables at the same time, you have selected the Use for new table and charts option, or this is a copy of a table that had the Rule already applied, this change will apply to all these instances of the Rule.
