Answer 1

You can use title function like this for get total of amount fields

const columns = [

    {
      title: () => { 
        var total = 0;
        for(var i=0;i<data.length;i++){
          total += data[i].amount;
        }
        return <div>total {total}</div>;
      } ,
      dataIndex: "date",
      width: 200
    },
    {
      title: "Amount",
      dataIndex: "amount",
      width: 100
    }
  ];
