将gota数据框的两列的最大值放在另一列中

I have below gota dataframe and I want to have another column which contains max value of column B and C.

this can be done easily with pandas dataframe, is there any way in Go also?

* go data frame

func main() {
    df := dataframe.LoadRecords(
        [][]string{
            []string{"A", "B", "C", "D"},
            []string{"a", "4", "5", "true"},
            []string{"k", "5", "7", "true"},
            []string{"k", "4", "2", "true"},
            []string{"a", "2", "1", "false"},
        },
    )
}

* Solution in python

df["Maximum"] = df[["B", "C"]].max(axis=1)
