help with databinding

You can bind a dataset to a datagrid like this.

this.dgResultsGrid.DataSource = ds;
this.dgResultsGrid.DataBind();

my colums are binded like this

<asp:Label id=Label1 runat="server" Text='<%# ((int)DataBinder.Eval(Container, "DataSetIndex")) + 1 %>'>

<asp:label id="Label3" runat="server">
<%# GetCharacterization(Container.DataItem)%>
</asp:label>

<asp:label id="Label2" runat="server">
<%# DataBinder.Eval(Container.DataItem, "Write")%>
</asp:label>

my questions
can i bind more then one tabel/datasetes to a datagrid?
can i bind per colum in my datagrid a different tabel/dataset?
