The System.Data.SqlClient.SqlDataReader or System.Data.OleDb.OleDbDataReader object which contains data.
Represents named range using IName enumeration. Bounds of data table should not greatfull than bounds of named range. i.e., Example NamedRange["A1:F6"] have a 6 Rows and 6 Columns. Also we should have DataTable rows and columns also same or lessthan named range.
TRUE if column names must be imported. FALSE otherwise.

Example
The following code illustrates how to Imports data from System.Data.IDataReader into worksheet.
using Syncfusion.XlsIO;
using System.Data;
             
class Example
{
  static void Main()
  {
     ExcelEngine excelEngine = new ExcelEngine();
     IApplication application = excelEngine.Excel;
     application.DefaultVersion = ExcelVersion.Excel2013;
     IWorkbook workbook = application.Workbooks.Create(1);
     IWorksheet worksheet = workbook.Worksheets[0];
        
     //Initialize named range
     IName namedRange = worksheet.Names.Add("SampleInfo");
     namedRange.RefersToRange = worksheet.Range["A1:F6"];
     
     //Initialize DataTable and get data from SampleDataTable method
     DataTable table = SampleDataTable();
     
     //Create IDataReader using Datatable 
     IDataReader reader = table.CreateDataReader();
  
     //Import data from DataReader
     worksheet.ImportDataReader(reader, namedRange, true);
     
     workbook.SaveAs("ImportDataReader.xlsx");
     workbook.Close();
     excelEngine.Dispose();
  } 
  
  static DataTable SampleDataTable()
  {
    // Here we create a three columns
    DataTable table = new DataTable();
    table.Columns.Add("ID", typeof(int));
    table.Columns.Add("Item", typeof(string));
    table.Columns.Add("Name", typeof(string));
            
    // Here we add four DataRows
    table.Rows.Add(1, "Soap", "David");
