When I press F5 error: warning error here: Cannot implicitly convert type 'void' to 'System.Data.DataTable'

public class NewDataSet : DataSet
    {
        public NewDataSet()
            : base()
        {
            DataTable dt = new DataTable("table");
            DataSetName = "NewDataSet";

            dt.Columns.Add("item_desc", typeof(string));
            dt.Columns.Add("Ins", typeof(int));
            dt.Columns.Add("Kg", typeof(int));
            dt.Columns.Add("Qty", typeof(int));
            dt.Columns.Add("Total", typeof(int));
            dt.Columns.Add("Date", typeof(DateTime));

            Tables.AddRange(new DataTable[] { dt });
        }

        public static NewDataSet CreateData(DataTable dta)
        {
            NewDataSet ds = new NewDataSet();
            DataTable dt = ds.Tables.Add(dta); // warning error here: Cannot implicitly convert type 'void' to 'System.Data.DataTable'

            return ds;
        }



        #region Disable Serialization for Tables and Relations
        [DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
        public new DataTableCollection Tables
        {
            get { return base.Tables; }
        }



        [DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
        public new DataRelationCollection Relations
        {
            get { return base.Relations; }
        }
        #endregion Disable Serialization for Tables and Relations

    }
