How to create excel sheet with multiple sheet name based on modules ?

I work on c# desktop app I Can't export data to excel file with multiple tab(multi sheet).

only that i can do create excel file with only sheet based on data exist on data table module field.

I use open XML library

Data table data as below :

Divide Output Excel File To Multi Tab based On Module

PartId Company Files Tab Module
1222 micro Abc source 1
1321 silicon Abc source 1
1444 cd2 Abc types 2
1321 cd3 Abc types 2
1541 tvs Abc types 2
Expected Result :

Create File ABC.xlsx with two sheet first sheet name source and second sheet name types based on module and load data related to every sheet based on data exist on data table.

so if I have two modules meaning I have two sheet .

What I have tried:

Code:

---

public Boolean createExcelFile(DataTable Table,String FullFilePathName)
      {
          Boolean IsDone = false;
          try
          {
              FileInfo CreatedFile = new FileInfo(FullFilePathName);
              Boolean ISNew = false;
              if (!CreatedFile.Exists)
              {

                  ISNew = true;
              }
              using (var pck = new ExcelPackage(CreatedFile))
              {
                  ExcelWorksheet ws;
                  if (ISNew == true)
                  {
                      ws = pck.Workbook.Worksheets.Add("Sheet");




                      ws.Cells[1, 1].LoadFromDataTable(Table, ISNew, OfficeOpenXml.Table.TableStyles.Light8);
                  }

                  else
                  {
                      ws = pck.Workbook.Worksheets.FirstOrDefault();
                      ws.Cells[2, 1].LoadFromDataTable(Table, ISNew);
                  }
                  pck.Save();
                  IsDone = true;

              }
          }
          catch (Exception ex)
          {

              throw ex;
          }
          return IsDone;
      }

but problem code above create one files with one sheet only

so How to create file with multi sheet based on module ?

Pseudo code

Code:

---

void FillExcelFileWithModuleData()
{
    using (var pck = new ExcelPackage(pathName))
    {
        // note: your code didn't have any examples of getting modules
        // this is an example of a list of modules where each item contains
        // a module name and data table
        foreach(var moduleData in modules)
        {
            var ws = ep.Workbook.Worksheets.Add(moduleData.Name);
            ws.Cells[1, 1].LoadFromDataTable(moduleData.Data, true, OfficeOpenXml.Table.TableStyles.Light8);
        }
        ep.Save();
    }
}

You can create multi sheet using Epplus like this

Code:

---

using(var package = new ExcelPackage())
{
    package.Workbook.Worksheets.Add("First worksheet 1", ws1);
    package.Workbook.Worksheets.Add("First worksheet 2", ws2);
    // Do something with the package
}
