Excel file writing error with Table Styles in EPPlus

Question

I have a requirement to write report the excel sheet with a style but

I am facing the error Tablename is not valid Parameter name: Name while trying to load the data table in an excel sheet using epplus with styles like below

 if (_ds.Tables[i].Rows.Count > 0)
 {
   _resultworkSheet.Cells["A1"].LoadFromDataTable(_ds.Tables[i], true, OfficeOpenXml.Table.TableStyles.Medium9);
 }

If I try to write the data table to excel sheet without table styles like below I am not facing any error

if (_ds.Tables[i].Rows.Count > 0)
{
  _resultworkSheet.Cells["A1"].LoadFromDataTable(_ds.Tables[i], true);
}

I am confused what could be causing the error while trying to load the excel sheet with styles anyone please shed a light on this to clear the error

Answer 1

I've never used the method your using, I do it like this

SelectedTable = Worksheet.Tables.Add(Range, tableName);
SelectedTable.TableStyle = _defaultTableStyle;

So if you grab the returned data and then set the style:

var data = _resultworkSheet.Cells["A1"].LoadFromDataTable(_ds.Tables[i], true);
data.TableStyle = OfficeOpenXml.Table.TableStyles.Medium9;

It's not one liner, but if it works:D
