How to pass a Datatable to Reportviewer?

Question

I receive the database query in a Datatable, I need to pass the datatable to a tablix in reportviewer by code, but when I run the tablix returns blank, I searched in several places and did not find an agile method to do this, follow the code...

private void frmRel_Load(object sender, EventArgs e)
    {
        this.report.RefreshReport();

        DataTable dt = RelatoriosModel.PesquisaTodos(); // RETORNA A TABELA DA CONSULTA NO SERVIDOR

        ReportDataSource reportDataSource = new ReportDataSource();

        this.report.LocalReport.ReportEmbeddedResource = "CifalApp.Logistica.Relatorios.Relatorio.rdlc";

        reportDataSource.Name = "DataSet1";
        reportDataSource.Value = dt;

        this.report.LocalReport.DataSources.Add(reportDataSource);
        this.report.RefreshReport();
    }
