in power query, if I want to operate one column, we will use _[columnName].
but if I want operate many column, I want use List.Transform({columnName1, columaname2},(t)=> operate(Table, [t]).
how to pass columnName var to operator this column?

If you can explain what exactly you are trying to do, then experts here can suggest the right solution.
When you are doing List.Transform({columnName1, columaname2},(t)=>, it is t which contains columnName1 & 2 one by one and whatever you are operating on t will be applicable on columnName1 & 2.
[t] , the t is only as a str, not as a var.
List.Transform({Column1,Column2},each List.Sum(Table.Column(tbl,_)))
