IListObject table = sheet.ListObjects.Create("Table", sheet.Range["A1:D4"]);
Step 4: Display total row.
table.DisplayTotalRow = true;
Step 5: Add a total row.
table.Columns[0].TotalsRowLabel = "Total"; table.Columns[1].TotalsCalculation = ExcelTotalsCalculation.Sum; table.Columns[2].TotalsCalculation = ExcelTotalsCalculation.Sum; table.Columns[3].TotalsCalculation = ExcelTotalsCalculation.Sum;
Step 6: Save the file.
