A data table is for storing info for the editor to use.
If you want to change variables on the fly though you should have it run of structures that all get updated when ever 1 is changed.
For example have a data table set up with all the beginning stats then at “begin play” have an array of structures set using the data table and then have that array updated anytime a player makes a change,
Remember a data table is really just an array of structures
