How do I use JSL to categorize positive and negative values in the same column?

[#1]

According to the data of the "weight" column in document "Arrhythmia" 、and the "criterion" file in the attachment, the "level" column is obtained.

Then, according to the "level" column and "class" column, the data of "V3 QRSTA" column are classified according to the following rules:
Row basis is "level", column basis is "class", and positive value and negative value of "V3 QRSTA" column are classified and summarized respectively.

The above operations can be easily completed with excel and its functions, but the speed is slow when the data volume is large.

If the amount of data is large, how to use JMP JSL should be completed more quickly.Thank you very much!
This problem is quite complicated. I made several pictures and uploaded 2 files.

Create a new character column in your data table. Use a formula to set the value in the column to a "+" if the column V3 QRSTA is greater than 0 and a "-" if below zero. Then do your Tables==>Summary and add the new column as an additional Group variable, keeping Class as your Subgroup, and Level as the Weight column

Ok, I see. That's the only way.

Thank Jim!
