All of what I am going to show you below is covered in the Using JMP book

What needs to be done is to create a new column in your data table, and apply a formula to the column.
1. Open the stacked data table and click on the red triangle in the column area above the row state column. Select "New Column"
2. The Column Info window will open. Change the name of the new column to whatever you want(I chose "Label 2"). Also change the Modeling Type to "Character"
3. Click on OK and then Right Click on the header area of the new column and select "Formula"
4. In the formula editor, double click on the box titled "No Formula"
5. Rather than doing the point and click formula building that we could do, with this simple formula, we just need to type it into the box
6. Once the typing is done, just click on OK or Apply and the formula will generate the new values
You can now use this new column in your Tabulate Platform
