How to make the grid field validated the sum 100% in Table Grid Next Generation

[jessiexjqin]

Hi There,

I'm new to Jira add-on "Table Grid Next Generation", does anyway auto sum a column in one Grid field to 100%? Example, now column A has only one value, it will be 100%; if A has two value, one is 20%, another should be 80%. Anyone know how to realize?
