C# Question

Is it possible to copy row (with data, merging, style) in Excel using Epplus?

The problem is that I need to insert data into Excel from the collection several times using a single template for the entire collection.

using (var pckg = new ExcelPackage(new FileInfo(association.TemplatePath)))
{
var workSheet = pckg.Workbook.Worksheets[1];
var dataTable = WorksheetToDataTable(workSheet);
/*Some stuff*/
FindAndReplaceValue(workSheet, dictionary, row);
}

private DataTable WorksheetToDataTable(ExcelWorksheet oSheet)
{
int totalRows = oSheet.Dimension.End.Row;
int totalCols = oSheet.Dimension.End.Column;
DataTable dt = new DataTable(oSheet.Name);
DataRow dr = null;
for (int i = 1; i <= totalRows; i++)
{
if (i > 1) dr = dt.Rows.Add();
for (int j = 1; j <= totalCols; j++)
{
if (i == 1)
dt.Columns.Add((oSheet.Cells[i, j].Value ?? "").ToString());
else
dr[j - 1] = (oSheet.Cells[i, j].Value ?? "").ToString();
}
}
return dt;
}


First picture - My template. Second - First element of collection (with data, style, merging). Third - Other elements has only data

This is my template
First element of collection has data, style, merging
Other elements got nothing besides data

I just make copies of rows

    for (int i = 0; i < invoiceList.Count; i++)
    {
        workSheet.Cells[1, 1, totalRows, totalCols].Copy(workSheet.Cells[i * totalRows + 1, 1]);
    }
