  {
    isBold = true,
    borderLeft = new()
    {
      style = BorderSetting.StyleValues.THICK
    },
    backgroundColor = "112233"
  });
// Use the Style Id
worksheet.SetRow("A1", new DataCell[6]{
  new(){
    cellValue = "test1",
    dataType = CellDataType.STRING,
    styleId = styleId
  }, new RowProperties()
