public static void WriteAndReadTableEpplusPolyform()
{
    string filePath = "SampleTable.xlsx";

    var t1 = SampleTableDyn01();
    CompuMaster.Data.XlsEpplusPolyformEdition.WriteDataTableToXlsFileAndFirstSheet(filePath, t1);

    System.Data.DataTable t = CompuMaster.Data.XlsEpplusPolyformEdition.ReadDataTableFromXlsFile(filePath, true);
    CompuMaster.Data.XlsEpplusPolyformEdition.WriteDataTableToXlsFileAndFirstSheet(filePath, t);

    System.Data.DataSet ds = CompuMaster.Data.XlsEpplusPolyformEdition.ReadDataSetFromXlsFile(filePath, true);
    CompuMaster.Data.XlsEpplusPolyformEdition.WriteDataTableToXlsFileAndFirstSheet(filePath, ds.Tables[0]);
}

private static System.Data.DataTable SampleTableDyn01()
{
    System.Data.DataTable t1 = new System.Data.DataTable("test");
    t1.Columns.Add();
    t1.Columns.Add();
    t1.Columns.Add();
    var r = t1.NewRow();
    r.ItemArray = new object[] { "1", "R1", "V1" };
    t1.Rows.Add(r);
    r = t1.NewRow();
    r.ItemArray = new object[] { "2", "R2", "V2" };
    t1.Rows.Add(r);
    r = t1.NewRow();
    r.ItemArray = new object[] { "3", "R3", "V3" };
    t1.Rows.Add(r);
    return t1;
