try to find out in the following way.

XML

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">

      <Columns>

          <asp:BoundField DataField="CompanyName"  HeaderText="Company"/>

          <asp:BoundField DataField="ContactName" HeaderText="Name"/>

          <asp:BoundField DataField="ContactTitle" HeaderText="Title"/>

          <asp:BoundField DataField="Address" HeaderText="Address"/>

      </Columns>

      </asp:GridView>

Have you write DataField="col1" as your dataTable Column

Also Check that Your DataTable has Data Or not
