I want to add a new row with only the "Total" label and the respective value.

  const csvContent = Papa.unparse(
    items.map(({ value1, value2, value3}, i) => {
      let item = {
        Index: i + 1,
        Name: value1,
        Value2: value2,
        Value3: value3,
      };
      return item;
    })
  );

The table looks like this:

 Index | Value1 | Value2 | Value3 
    1  |  value |  ...   |  ....
    2  |   ...  |  value |  ....
    3  |   ...  |  ...   |  value

And I want it to be like this

 Index | Value1 | Value2 | Value3 
    1  |  value |  ...   |  ....
    2  |   ...  |  value |  ....
    3  |   ...  |  ...   |  value
    
    Total                     234234

*With an empty row between the last table row and the total row
