how to select the next 10 rows of a datatable c#

I have a Master DataTable that does not have a primary key,

I want to be able to get rows 0 to 9 of the Master and put them in datatable 1
rows 10 to 19 into datatable 2
rows 20 to 26 into datatable 3

Here is the function i have designed so far but now I am stuck on trying to find out how to loop through the rows ...

       private DataSet CreateCachedPagedDataTables(DataTable MasterDataTable, PagedDataSource PagedDataInformation)
        {
            DataSet dataSet = new DataSet();
            string DTName = "";
            int z = 0;

            for (int i = 0; i < PagedDataInformation.PageCount; i++)
            {
                //create a datatable
                DTName = "Page" + i.ToString();
                DataTable dt = new DataTable(DTName);

                //loop through the master data table by pagecount
                //check if the row is there
                for (int j = 0; j < PagedDataInformation.PageSize; j++)
                {

                    //add each row of MasterDataTable
                    //to the datatable just created

                    //how to add the row??

                   
                    //how to reset the starting postion ofthe row
                    z++;
                }

                //add this datatable to the DataSet
                dataSet.Tables.Add(DTName);
            }


            return dataSet;
        }
